Question

What is x^2-12x+36 in factored form?

Answer 1

For this case we must factor the following expression:

$x ^ 2-12x + 36$

We must find two numbers that when multiplied give as a result "36" and when added together they give "-12". These numbers are:

$-6-6 = -12\\-6 * -6 = 36$

Then, the factorization is given by:

$(x-6) (x-6) = (x-6) ^ 2$

Answer:

$(x-6) ^ 2$
