Question

Expand (n+5)^2 by rewriting the expression a multiplication of n 5 by itself and using the FOIL

Answer 1

$(n+5) ^{2} = (n+5)(n+5)$

Now we use FOIL to rewrite the expression.

FOIL is:
First
Outer
Inner
Last

That's the order we will be distributing the variables in the parentheses.

$n^{2} + 5n +5n +25$

Combine like terms:
$n^{2}+10n+25$

That's your final answer.

Hope that helps.
