Question

What is the factored form of n^2 + n

A. n(n + n)
B. n(n - 1)
C. 2(n + n)
D. 2(n + 1)

Answer 1

n^2 + n


if you divide the whole thing by n

you will see that n^2/n =n
and n/n=1

therefore n(n+1)

Answer 2

A. n(n+1), just factor out a "n" form the equation and you are left in parenthesis.
