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

We can use perfect square trinomial method

Step-by-step 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 ...

perfect-square trinomial
