Answer: n squared plus 10 n plus 25

Explanation:

To make the expression a perfect square:

add a term that is equal to half the coefficient of n, squared.

the coefficient of n is 10, so half of it is 5

add 5 squared, or 25, to the expression:

n squared plus 10 n plus 25

this expression can be factored into (n+5) squared, which is a perfect square.
