Step-by-step polynomial long division example showing how to divide f(x) = x³ - 2x² - 3x + 10 by (x + 2), resulting in (x + 2)(x² - 4x + 5).
A step-by-step guide to polynomial long division showing the division of f(x) = x³ - 2x² - 3x + 10 by (x + 2), with labeled steps including multiply, subtract, and bring down, resulting in f(x) = (x + 2)(x² - 4x + 5). Includes a graph of the function and a note about using the quadratic formula to find imaginary zeros.
