If answer is correct I will mark as brainliest. Which of the binomials below is a factor of this trinomial?

x^2-13x+42

A. x + 84

B. x^2 + 12

C. x - 7

D. x + 7

When we look at the trinomial, there is no number (coefficient) in front of x² , so we know that it is a simple trinomial. All you have to do in a simple trinomial is to find two numbers that not only add up to the b term, but multiply to the c term.

In this trinomial, the b term is 13 , so you need to find two numbers that add up to 13 . That could be

and so on. But these two numbers need to multiply to get the c term. In this case, it's 42 . So what two numbers add up to 13 and multiply to 42 ? The answer is 6 and 7 .

and

After this, all you need to do is put this in binomial form, so take an x , and add your first number

sine
