(2x + 5) × (x² + 6x − 10)

\bold\pink{↪}\bold\red{2x³ + 12x² - 20x + 5x² + 30x - 50}

Answer:


(2x + 5) * (x^(2) + 6x - 10)\\= 2x (x^(2) + 6x - 10) + 5 (x^(2) + 6x - 10)\\= 2x^(3) + 12x^(2) - 20x + 5x^(2) +30x - 50\\= 2x^(3) + 12x^(2) + 5x^(2) - 20x + 30x - 50\\= \boxed{2x^(3) + 17x^(2) + 10x - 50}

Hope it helps ⚜
