Question

Factor the expression below x^2 - 10x + 25

Answer 1

It would be (x-5)(x-5)

Answer 2

find factors of x² and 25 that, when added together, will = -10x

x² - 10x + 25
x              -5
x              -5

(x - 5)(x - 5) = 0 should be your answer

x - 5 = 0
x - 5 (+5) = 0 (+5)
x = 5

If you are looking for x, x = 5

hope this helps
