Question

Quizplus · Accepted Answer

To divide the polynomial $- 42 x ^ { 2 } - 21 x + 28$ by 7, each term of the polynomial is divided by 7 individually. This results in $- 42 x ^ { 2 } / 7 = - 6 x ^ { 2 }$, $- 21 x / 7 = - 3 x$, and $28 / 7 = 4$, giving the simplified expression $- 6 x ^ { 2 } - 3 x + 4$.
