Question 236721: Divide
4x%5E2%2B7%2B8x%5E3
____________
2x+3
I rewrote numerator as 8x%5E3%2B4x%5E2%2B7 (decending order)
I always have a hard time factoring these problems...could I use the AC method?
Thank you

You were correct in rewriting the numerator. Here's long division with polynomials:
     4x^2  + (-4x)  +   6
     ________________________________
2x+3/8x^3  +  4x^2  +   0x  +    7
     8x^3  + 12x^2
     -------------
             -8x^2  +   0x
             -8x^2  + -12x
             -------------
                       12x   +   7
                       12x   +  18
                       -----------
                               -11

So
