Which of the binomials below is a factor of this trinomial ? X^2-5x-14 A.x-1 B.x-14 C.x-2 D.x-7

OpenStudy (will.h):

\[x^2 - 5x - 14\] Find 2 numbers with sum of -5 and when multiplied = - 14 i gues it would be -7 and 2 \[(x^2 - 7x ) (2x - 14)\] Now factor those by groups obviously GCF of the 1st binomial is x so x(x - 7) GCF of the 2nd binomial is 2 so 2(x - 7) The factored expression is \[(x + 2 ) ( x - 7)\]
