EXPLANATION
We want find the term among the given options that can be added to
That term must be similar to the given term.
It means that,it must be a
term.
From the alternatives provided, the only term, that is similar to the given term is
Therefore, the correct answer is C
In this case we have the following trinomial:
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:
So, we have:
