Question

How do you divide (4x^3-2x+7) / (2x+1) also it needs to express the answer in the form Q(x)= ?, r(x)=? and needs to use long division.

long division is a pain to write here, almost impossible
if you want to see the steps, scroll down to "quotient and remainder" and click on "show steps"
it will show you the long division
