Question

Combine like terms (x+5)(x-5)=

Answer 1

x^2 - 25

Explanation:

-you first do x times x, you get x squared or x^2

-then you do x times -5, you'll get -5x

-then do 5 times the x, you get 5x

-since -5x and 5x are opposites, they cancel out.

-and finally you do 5 times -5 which is -25

-with all of it done you get x^2 (x squared) + 25

Answer 2

x^2 -5x+5x - 25
Final answer : x^2 -25
