What is the factorization of the expression below?
x2-12x + 36
o
o a. (x + 6)(x-6)
o b. (x + 4)(x-9)
o c. (x-4)(x-9)
o d. (x-6)(x-6)

D. (x-6)(x-6)

Step-by-step explanation:

We have the following trinomial, which is also known as perfect square trinomial, because the first and the third term are squares:

 (1)

First term:  

Third term:  

If we factorize this expression we have:

As we can see, the trinomial (1) has two factors:

and

Therefore, the correct option is D.

12/11c

or

12

c
