Question

The polynomial below is a perfect square trinomial of the form A2 - 2AB + B2.

Answer 1

Answer: B

Explanation:

Answer 2

Answer: Option B.

Explanation:

Given the polynomial:

`16x^2-36x+9`

Observe that
`16x^2` and
`9` are perfect squares. Then, you can rewrite the polynomial in this form:

`(4x)^2-36x+(3)^2`

You can identify that:

`A=4\\B=3`

Then, we can check if
`2AB=36`

`2(4x)(3)=36x\\\\24x\\eq 36x\\\\2AB\\eq36x`

Since
`2AB\\eq36x`, the polynomial
`16x^2-36x+9` IS NOT a perfect square trinomial of the form
`A^2 - 2AB + B^2`
