Question

how do I factor a2-25

Answer 1

(a+5)*(a-5)

Answer 2

ok, since it has no a in the middle, u need a + and a - in both solutions to cancel out the x.

so it would be:

(a+5)(a-5)=0

The 5a's would cancel out each other.

Answer 3

difference of squares

Answer 4

this is called the difference of two squares since a^2-b^2 = (a-b)(a+b)
