n²-25
Explanation:
Expand the polynomial using the FOIL method. (A handy way to remember how to multiply two binomials. It stands for "First, Outer, Inner, Last")
Answer:
n² - 25
Step-by-step explanation:
(n - 5)(n + 5)
Each term in the second factor is multiplied by each term in the first factor, that is
n(n + 5) - 5(n + 5) ← distribute parenthesis
= n² + 5n - 5n - 25 ← collect like terms
= n² - 25
