Question

What value in place of the question mark makes the polynomial below a perfect square trinomial?



A. 22
B. 44
C. 121
D. 11

Answer 1

The polynomial below?

Answer 2

Sorry,

x^2 +22x =?

Answer 3

\[\large\rm x^2+bx\]Take half of your b-coefficient and square it,\[\large\rm \left(\frac{b}{2}\right)^2\]So for your polynomial, that means do those things to the 22, ya?

Answer 4

So,

(22/2)^2

Answer 5

Yes.

Answer 6

So, is that my final answer?

Answer 7

Well that's not one of the answer choices :) lol
So no.

You'll have to simplify it.

Cut 22 in half (that's 11, right?)
then square it.

Answer 8

121

Answer 9
