Question

Quizplus · Accepted Answer

Synthetic division of $x^3 - 48x + 128$ by $x - 4$ yields a quotient of $x^2 + 4x - 32$.

Use Synthetic Division to Divide (x3−48x+128)÷(x−4)\left( x ^ { 3 } - 48 x + 128 \right) \div ( x - 4 )(x3−48x+128)÷(x−4)

Use Synthetic Division to Divide $\left( x ^ { 3 } - 48 x + 128 \right) \div ( x - 4 )$
