multiplicacion de polinomios ayuda!!!!

Answer 1

$\left(5x^3+3x^2-3x+4\right)\left(-4x^3+2x-6\right)$

$=5x^3\left(-4x^3\right)+5x^3\cdot \:2x+5x^3\left(-6\right)+3x^2\left(-4x^3\right)+3x^2\cdot \:2x+3x^2\left(-6\right)+\left(-3x\right)\left(-4x^3\right)+\left(-3x\right)\cdot \:2x+\left(-3x\right)\left(-6\right)+4\left(-4x^3\right)+4\cdot \:2x+4\left(-6\right)$

$=-5.4x^{3}x^{3}+5.2x^{3}x-5.6x^{3}-3.4x^{3}x^{2}+3.2x^{2}x-3.6x^{2}+3.4x^{3}x-3.2xx+3.6x-4.4x^{3}+4.2x-4.6$

$=-20x^6-12x^5+22x^4-40x^3-24x^2+26x-24$
