Answer
36
Work Step by Step
$(6p+5)^{2}$
Use FOIL to simplify. FOIL: First (Multiply the first variables in the brackets), outside (Multiply the outer variables), Inside (Multiply the inside variables), Last (Multiply the last variables in the brackets).
(6p)(6p) + 5(6p) + 5(6p) + (5)(5) $36p^{2}$ + 30p + 30p + 25
We add the 30p and 30p to get the simplified answer.
$36p^{2}$ + 60p + 25
Thus the first term is $36p^{2}$ and thus the missing number is 36.
