Question

If a polynomial has three terms, x2 + 12x + 36, which factoring method can be considered?

Answer 1

perfect-square trinomial

Explanation:

Answer 2

We can use perfect square trinomial method

Explanation:

We can use perfect square trinomial method.

We have the expression x2 + 12x + 36

The first and third term of this expression are perfect square:

Perfect square of x^2 = x

Perfect square of 36 is 6

So we can use the formula:

(a^2+2ab+b^2) =(a+b)^2

For given expression:

(x2 + 12x + 36) = (x+6)^2 ....
