Perform the indicated operation.
-$\left( 18 x ^ { 2 } + 11 \right) - \left( 6 x ^ { 2 } - 6 \right)$
A) $24 x ^ { 2 } + 5$
B) $12 x ^ { 2 } + 17$
C) $24 x ^ { 2 } + 17$
D) $12 x ^ { 2 } + 5$

Question

Quizplus · Accepted Answer

Subtracting the second polynomial from the first gives $18x^2 + 11 - (6x^2 - 6) = 18x^2 + 11 - 6x^2 + 6 = 12x^2 + 17$.

Perform the Indicated Operation (18x2+11)−(6x2−6)\left( 18 x ^ { 2 } + 11 \right) - \left( 6 x ^ { 2 } - 6 \right)(18x2+11)−(6x2−6)
