Solve this equation by taking square roots: r^2-9=-16

To solve the equation r^2 - 9 = -16 by taking square roots, follow the steps below:

1. Add 9 to both sides of the equation to isolate the squared term on one side:
   r^2 = -16 + 9
   r^2 = -7

2. Take the square root of both sides of the equation to solve for r:
   √(r^2) = √(-7)

   Note: When dealing with square roots of negative numbers (√(-7)), we need to introduce the concept of complex numbers.

   The square root of a negative number can be represented as the imaginary unit, "i," times the square root of the positive value. Hence, √(-1) = i.

3. Applying this concept to our equation:
   r = ± √(-7)
   r = ± (√7)i

Therefore, the solution to the equation r^2 - 9 = -16 by taking square roots is r = ± (√7)i, where "i" represents the imaginary unit.

Solve this equation by taking square roots: p^2+1=101

To solve the equation p^2 + 1 = 101 by taking square roots, follow the steps below:

1. Subtract 1 from both sides of the equation to isolate the squared term on one side:
   p^2 = 101 - 1
   p^2 = 100

2. Take the square root of both sides of the equation to solve for p:
   √(p^2) = √100

   The square root of 100 is 10.

3. Considering both the positive and negative square roots:
   p = ± 10

Therefore, the solution to the equation p^2 + 1 = 101 by taking square roots is p = ±10.

Solve this equation by taking square roots: 2n^2=72

To solve the equation 2n^2 = 72 by taking square roots, follow the steps below:

1. Divide both sides of the equation by 2 to isolate the squared term on one side:
   n^2 = 72/2
   n^2 = 36

2. Take the square root of both sides of the equation to solve for n:
   √(n^2) = √36

   The square root of 36 is 6.

3. Considering both the positive and negative square roots:
   n = ±6

Therefore, the solution to the equation 2n^2 = 72 by taking square roots is n = ±6.

Solve this equation by taking square roots: m^2-4=-8

To solve the equation m^2 - 4 = -8 by taking square roots, follow the steps below:

1. Add 4 to both sides of the equation to isolate the squared term on one side:
   m^2 = -8 + 4
   m^2 = -4

2. Take the square root of both sides of the equation to solve for m:
   √(m^2) = √(-4)

   Note: When dealing with square roots of negative numbers (√(-4)), we need to introduce the concept of complex numbers.

   The square root of a negative number can be represented as the imaginary unit, "i," times the square root of the positive value. Hence, √(-1) = i.

3. Applying this concept to our equation:
   m = ± √(-4)
   m = ± 2i

Therefore, the solution to the equation m^2 - 4 = -8 by taking square roots is m = ±2i, where "i" represents the imaginary unit.

Solve this equation by taking square roots: -10n^2=-230

To solve the equation -10n^2 = -230 using square roots, follow the steps below:

1. Divide both sides of the equation by -10 to isolate the squared term on one side:
   n^2 = (-230)/(-10)
   n^2 = 23

2. Take the square root of both sides of the equation to solve for n:
   √(n^2) = √23

   Since 23 is a positive number, the square root of 23 can be represented as both a positive and negative value.

3. Considering both the positive and negative square roots:
   n = ±√23

Thus, the solution to the equation -10n^2 = -230 using square roots is n = ±√23.

Solve this equation by taking square roots: 81x^2=9

To solve the equation 81x^2 = 9 by taking square roots, follow the steps below:

1. Divide both sides of the equation by 81 to isolate the squared term:
   x^2 = 9/81
   x^2 = 1/9

2. Take the square root of both sides of the equation to solve for x:
   √(x^2) = √(1/9)

   The square root of (1/9) can be expressed as both positive and negative values.

3. Considering both the positive and negative square roots:
   x = ±1/3

Therefore, the solution to the equation 81x^2 = 9 by taking square roots is x = ±1/3.

Solve this equation by factoring: p^2-8p=0

To solve the equation p^2 - 8p = 0 by factoring, follow the steps below:

1. Rewrite the equation: p^2 - 8p = 0.

2. Factor out the common term p from both terms:
   p(p - 8) = 0.

3. Apply the zero product property, which states that if a product of factors equals zero, then at least one of the factors must be zero. Set each factor equal to zero and solve for p:

   Setting p = 0:
   p = 0.

   Setting p - 8 = 0:
   p - 8 = 0
   p = 8.

Therefore, the solutions to the equation p^2 - 8p = 0 by factoring are p = 0 and p = 8.

Solve this problem by factoring: 7m^2-30m+8=0

To solve the quadratic equation 7m^2 - 30m + 8 = 0 by factoring, follow the steps below:

1. Multiply the coefficient of the quadratic term (7) by the constant term (8):
   7 * 8 = 56.

2. Find two numbers that multiply to give 56 and add up to give the coefficient of the linear term (-30). In this case, the numbers are -4 and -14:
   -4 * -14 = 56,
   -4 + (-14) = -18.

3. Rewrite the middle term (-30m) using -4m and -14m:
   7m^2 - 4m - 14m + 8 = 0.

4. Group the terms and factor by grouping:
   (7m^2 - 4m) - (14m - 8) = 0,
   m(7m - 4) - 2(7m - 4) = 0.

5. Notice that (7m - 4) is common to both terms. Factor it out:
   (7m - 4)(m - 2) = 0.

6. Apply the zero product property, stating that if a product of factors equals zero, then at least one of the factors must be zero. Set each factor equal to zero and solve for m:

   Setting 7m - 4 = 0:
   7m = 4,
   m = 4/7.

   Setting m - 2 = 0:
   m = 2.

Therefore, the solutions to the quadratic equation 7m^2 - 30m + 8 = 0 by factoring are m = 4/7 and m = 2.

Solve the equation using the quadratic formula: 4n^2-5=-2n

To solve the equation 4n^2 - 5 = -2n using the quadratic formula, we can follow these steps:

1. Rearrange the equation, so we have 4n^2 + 2n - 5 = 0. 

2. Identify the coefficients a, b, and c. In this case, a = 4, b = 2, and c = -5.

3. Apply the quadratic formula: 
   n = (-b ± √(b^2 - 4ac)) / (2a).

4. Substitute the values of a, b, and c into the formula:
   n = (-(2) ± √((2)^2 - 4(4)(-5))) / (2(4)).

5. Simplify the equation:
   n = (-2 ± √(4 + 80)) / (8).
   n = (-2 ± √(84)) / 8.
   n = (-2 ± √(4 * 21)) / 8.
   n = (-2 ± 2√21) / 8.

6. Further simplify and split the equation into two separate solutions:
   n = (-2 + 2√21) / 8 and n = (-2 - 2√21) / 8.

Therefore, the solutions to the equation 4n^2 - 5 = -2n using the quadratic formula are:
n = (-2 + 2√21) / 8 and n = (-2 - 2√21) / 8.
