A) $( x + 2 ) ( x + 7 )$
B) $( x + 1 ) ( x + 14 )$
C) $( x - 2 ) ( x - 7 )$
D) $( x - 1 ) ( x - 14 )$
E) $( x - 1 ) ( x + 14 )$

Question

Quizplus · Accepted Answer

The correct factorization of $x^2 + 15x + 14$ is found by looking for two numbers that multiply to 14 and add up to 15. Those numbers are 1 and 14, making the correct factorization $(x + 1)(x + 14)$.
