Question

If this is a perfect square trinomial factor it

A: (x-6)^2
B: (x+6)^2
C: (x(6)(x-12)
D: it's not a perfect square trinomial​

Answer 1

Option B:
`(x + 6)^2`

Explanation:

Hello!

We can simply expand each option to find which one matches the trinomial
`x^2 +12x + 36`

A: (x - 6)²

• (x - 6)(x - 6)
• x² - 6x - 6x + 36
• x² - 12x + 36

It does not match.

B:(x + 6)²

• (x + 6)(x + 6)
• x² + 6x + 6x + 36
• x² + 12x + 36

Option B matches, so it is the right solution.
