Question

Quizplus · Accepted Answer

Using polynomial long division, dividing $12x^3 + 27x^2 + 31x + 20$ by $-4x - 5$ results in $-3x^2 - 3x - 4$.

Divide - (12x3+27x2+31x+20)÷(−4x−5)\left( 12 x ^ { 3 } + 27 x ^ { 2 } + 31 x + 20 \right) \div ( - 4 x - 5 )(12x3+27x2+31x+20)÷(−4x−5)

Divide
- $\left( 12 x ^ { 3 } + 27 x ^ { 2 } + 31 x + 20 \right) \div ( - 4 x - 5 )$
