Question

X^2 +x - 30 which on the binomials below is a factor of this trinomal? a . X-3 B. X-6 C. X+6D. X+3

Answer 1

ANSWER:

C. x+6

STEP-BY-STEP EXPLANATION:

We have the following expression

$x^2+x-30$

We factor by identifying two numbers that multiplied equals -30 but added equals +1

$\begin{gathered} 6\cdot-5=-30 \\ 6-5=1 \\ (x+6)\cdot(x-5) \end{gathered}$

Therefore the answer is x + 6
