Question

Multiply (2x+5) times (x2+6x-10) ? Thank you:)

Answer 1

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 ⚜

Answer 2

$(2x + 5) × (x² + 6x − 10)$

$\bold\pink{↪}\small\bold\red{2x(x² + 6x − 10) +5(x² + 6x − 10)}$

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

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

$\bold\pink{↪}\bold\red{2x³ + 17x² + 10x - 50}$
