Question

Expand.
If necessary combine like terms.
(x+5)(x-5)​

Answer 1

x^2-25

Step-by-step explanation:

We apply the formula (a-b)(a+b) = a^2*b^2. Substituting x for a and 5 for b, we get the answer x^2-25.

Answer 2

x²−25

Step-by-step explanation:

(x+5)(x−5)

=(x+5)(x+−5)

=(x)(x)+(x)(−5)+(5)(x)+(5)(−5)

=x²−5x+5x−25

=x²−25
