Find the missing monomial, factor or term.
-$$( x + 10 ) \cdot ? = x ^ { 2 } - 100$$
A) $x ^ { 2 } - 10$
B) $x + 10$
C) $x ^ { 2 } + 20$
D) $x - 10$

Question

Quizplus · Accepted Answer

The correct factor to complete the equation $( x + 10 ) \cdot ? = x ^ { 2 } - 100$ is $x - 10$, because when you multiply $(x + 10)$ by $(x - 10)$, you get $x^2 - 100$ using the difference of squares formula.
