Find the solutions to the equation below.

Check all that apply.

x2 - 25 = 0

A. X = 3

B. x = - 5

C. X = 1

D. X = - 3

E. x = 5

I F. x = - 1

Answer: x = + 5

Explanation: To solve the equation x² - 25 = 0, our first step is to get the x² term by itself by adding 25 to both sides of the equation.

On the left side of the equation, the - 25 and + 25 cancel out and we have x² and on the right side of the equation, 0 + 25 is 25.

So we have x² = 25².

Now to get x by itself, we take the square

root of both sides of the equation.

On the left, the square root of x² is x snd on the right, since 25is the perfect square 5 · 5, the square root of 25 is 5 and don't forget to use plus or minus when taking the square root of both sides of an equation.

So our answer is x = + 5.

x = - 5, 5

Step-by-step explanation:

x^2 - 25 = 0

Add 25 to each side

x^2 - 25+25 = 0+25

x^2 = 25

Take the square root on each side

sqrt (x^2) = ±sqrt (25)

x = ±5
