If a polynomial has three terms, x^2 + 12x + 36, which factoring method can be considered? a.) perfect-square trinomial b.) difference of squares c.) sum of cubes d.) difference of cubes

A.) perfect-square trinomial.

Step-by-step explanation:

We have been given a polynomial . We are asked to determine the factoring method that can be considered.

We can see that our given polynomial is in form , where, and .

We can rewrite our given expression as a perfect-square trinomial as:

Therefore, we will use perfect-square trinomial  to factor the given trinomial.

The answer is C. 5.6.

First combine the like terms of the equation.

6+5.6-x=6

6+5.6=11.6

11.6-x=6

Then subtract 11.6 from both sides of the equation.

11.6-11.6-x=6-11.6

-x=-5.6

Then divide both sides by -1.

=

x=5.6
