Factor out the greatest common factor. Simplify the factors, if possible.
-$$( x - 9 ) ( x + 7 ) + ( x - 9 ) ( x + 7 )$$
A) $2 ( x - 9 ) ( 2 x + 14 )$
B) $2 ( x - 9 ) ( x + 7 )$
C) $( x - 9 ) ( 2 x + 14 )$
D) $( x - 9 ) ( x + 14 )$

Question

Quizplus · Accepted Answer

The expression can be simplified by factoring out the common factor $(x - 9)(x + 7)$, which appears twice, resulting in $2(x - 9)(x + 7)$.

Factor Out the Greatest Common Factor (x−9)(x+7)+(x−9)(x+7)( x - 9 ) ( x + 7 ) + ( x - 9 ) ( x + 7 )(x−9)(x+7)+(x−9)(x+7)

Factor Out the Greatest Common Factor $( x - 9 ) ( x + 7 ) + ( x - 9 ) ( x + 7 )$
