Multiply : x^2 + x + 1 by 1 - x

Question

KnowledgeBoat · Accepted Answer

(x² + x + 1) (1 - x) = 1 (x² + x + 1) - x (x² + x + 1) = (1 x² + 1 x + 1 1) - (x x² + x x + x 1) = x² + x + 1 - (x³ + x² + x) = x² + x + 1 - x³ - x² - x = (x² - x²) + (x - x) + 1 - x³ = 1 - x³ Hence, (x² + x + 1) (1 - x) = 1 - x³
