Multiply the two brackets together
(x+5)(x-5)
(x)(x)(-5)(x)(+5)(x)(5)(-5)
x^2-5x+5x-25
x^2-25
Answer: x^2-25 ( third choice)
Answer:
x^2 − 25
Step-by-step explanation:
(x + 5)(x − 5)
which is then
x(x − 5) and 5(x − 5)
= x^2 -5x + 5x - 25
-5x and 5x cancel each other out, so you're left with
x^2 − 25
