Divide polynomials using long division

Problem

Use the polynomial long-division setup to divide \(x^3~+~2x^2~-~5x~+~6\) by \(x~+~3\). State the quotient and remainder.

Big Picture

What this problem is really about

Polynomial long division is a repeating leading-term process. Keep like powers aligned, divide the current leading term by the divisor’s leading term, multiply the entire divisor by that quotient term, and subtract every term in the row. Repeat until the remainder has lower degree than the divisor, then verify with dividend equals divisor times quotient plus remainder.
