Hey there!

x^2-25=0

The first step we have to do is to add 25 to both sides of the equation.

$x^2-25+25=0+25\\\text {equals }x^2=25$

In our last and final step, we will have to take the square root.

±
√(25)

We have two answers.

$x=5(ANSWER)\\x=-5(ANSWER)$

Hope this helps!

Answer:

x=5,x=-5

Step-by-step explanation:

x^2-25=0

Add 25 to both sides:

x^2-25+25=0+25

x^2=25

Square root both sides:

$x=√(25),\:x=-√(25)$ (Since a negative number multiplied by itself gives positive, there are two answers.)

x=5,x=-5
