Answer:
Step-by-step explanation:
According to the question,
Factoring
The first term is, its coefficient is 1.
The middle term is, its coefficient is 13.
The last term, "the constant", is -48.
the polynomial splitting the middle term using the two factors found above, -16 and 3
Add up the first 2 terms, pulling out like factors :
Add up the last 2 terms, pulling out common factors :
Add up the four terms:
Which is the desired factorization.
the solution is -16 and 3.
