Factor the trinomial, if possible.
-$$x ^ { 2 } + 2 x y - 99 y ^ { 2 }$$
A) $( x - 11 y ) ( x + 9 y )$
B) prime
C) $( x + 11 y ) ( x - 9 y )$
D) $( x - 11 y ) ( x + y )$

Question

Quizplus · Accepted Answer

The trinomial can be factored by finding two numbers that multiply to $-99y^2$ and add to $2y$. These numbers are $11y$ and $-9y$, leading to the factorization $(x + 11y)(x - 9y)$.

Factor the Trinomial, If Possible x2+2xy−99y2x ^ { 2 } + 2 x y - 99 y ^ { 2 }x2+2xy−99y2

Factor the Trinomial, If Possible $x ^ { 2 } + 2 x y - 99 y ^ { 2 }$
