Answer:
(3p + 5)^2
Step-by-step explanation:
9p^2 + 30p + 25
9p^2 is the square of 3p = a
25 is the square of 5 = b
This may be the square of a binomial.
We need to check the middle term.
(a + b)^2 = a^2 + 2ab + b^2
2ab = 2(3p)(5) = 30p
This is the square of a binomial.
9p^2 + 30p + 25 = (3p + 5)^2
