Answer 1

Respuesta:

$56am^2x^2-35am^2x+77am^2+40x^3-25x^2+55x-24mx^3+15mx^2-33mx$

Explicación paso a paso:

$=7am^2\times \:8x^2+7am^2\left(-5x\right)+7am^2\times \:11+5x\times \:8x^2+5x\left(-5x\right)+5x\times \:11+\left(-3mx\right)\times \:8x^2+\left(-3mx\right)\left(-5x\right)+\left(-3mx\right)\times \:11$

$=7\times \:8am^2x^2-7\times \:5am^2x+7\times \:11am^2+5\times \:8x^2x-5\times \:5xx+5\times \:11x-3\times \:8mx^2x+3\times \:5mxx-3\times \:11mx$

$=56am^2x^2-35am^2x+77am^2+40x^3-25x^2+55x-24mx^3+15mx^2-33mx$
