Question

Factor each expression completely.

x^2 - 25

Answer 1

we can write it in the form of

x^²-5^²

we know that it's a form of (a^²-b^²)

(a+b) (a-b)

so, (X+5) (x-5)

hope it help you

Answer 2

Rewrite it in the form a^2 - b^2, where a = x and b = 5

x^2 - 5^2

Use the Difference of Squares: a^2 - b^2 = (a + b)(a - b)

= (x + 5)(x - 5)
