Question

Divide: (3x^4+11x^3+10x^2+5x-21) / ( x+3). Synthetic division is recommended, but you can use long division too

Answer 1

Quotient Is 3x³+2x²+ 4x-7 and the remainder is 0.

Explanation:

In long division, first we have to multiply (x+3) by 3x³, and then changing the sign of the product, cancel the terms then (x+3) is multiplied by 2x² then by 4x and finally by -7, we will get the remainder as 0 and the quotient as 3x³+2x²+ 4x-7.
