Consider 6x2 + 6x + 1. which term immediately tells you that this expression is not a perfect square trinomial? justify your answer.

a) 1; one has factors of 1 and -1.
b) 6x2; six is not a perfect square.
c) 6x; six is not a perfect square.
d) 6x2; six is a composite number.

Option B

Step-by-step explanation:

Given is a quadratic expression as

This is not a perfect square because the last term 1 is a perfect square.

So if the whole term is to be a perfect square since last term is a perfect square the leading term also has to be a perfect square.

But 6x square though x square is a square 6 is not a perfect square

So this cannot be a perfect square

Answer is

Option B.
