Quizplus · Accepted Answer

Subtracting $(12a^2b - 9ab)$ from $(10a^2b - 13ab)$ gives $(10a^2b - 13ab) - (12a^2b - 9ab) = 10a^2b - 13ab - 12a^2b + 9ab = -2a^2b - 4ab$.

Simplify -Subtract (12a2b−9ab)\left( 12 a ^ { 2 } b - 9 a b \right)(12a2b−9ab)

Simplify
-Subtract $\left( 12 a ^ { 2 } b - 9 a b \right)$
