Factor the trinomial, if possible.
-$$x ^ { 2 } + 5 x y - 14 y ^ { 2 }$$
A) $( x + 7 y ) ( x - 2 y )$
B) $( x - 7 y ) ( x + y )$
C) $( x - y ) ( x + 2 y )$
D) $( x - 7 y ) ( x + 2 y )$

Question

Quizplus · Accepted Answer

The correct factorization is found by looking for two numbers that multiply to $-14y^2$ and add to $5y$. These numbers are $7y$ and $-2y$, leading to the factorization $(x + 7y)(x - 2y)$.
