Add 25 to both sides of the equation to get....
x^2 = 25
then take the square root of both sides,
x = + or - sqrt (25) = + or - 5
x has two possible values, 5 and -5, since both of these squared will yield 25.
(5)^2 = 25
(-5)^2 = 25

x^2-25=0 add 25 to the right side (this removes it from the left)
x^2=25
x^2=25 means x squared is equal to 25, so you find the square of 25.
x=5 or -5 because 5 x 5 = 25 and -5 x -5 = 25
does that help?

You first add 25 to both sides. This will give you x^2= 25. After this you find the square root of both sides ( the square root of x^2 and the square root of 25). Your answer should be x=5 or x= -5

x^2-25=0
(x^2-25)+25=0+25
x^2=25
x=square root of 25 = 5 (or -5)

Add 25 to both sides then do the square root of both sides. Don't forget that when you do this the answer could be positive or negative so include both.
