Which of the binomials below is a factor of this trinomial ? X^2 -13+42
lapo4ka [179]

In this case we have the following trinomial:

x ^ 2 -13x + 42

By definition, the factorization is a technique that consists in the mathematical decomposition of an expression, in the form of a product. Having said that, we can factor the given trinomial in the following way:

We look for two numbers that when multiplied give as result 42, and when summed give as result -13.

The numbers that meet these two conditions are -6 and -7 by:

-6 * -7 = 42\\-6-7 = -13

So, we have:

(x-6) (x-7)

Answer:

The binomials associated with the given trinomial are(x-6) and (x-7).
