Question

d the expression to a polynomial in standard form
$(3x - 4)(2x^2 - 5x - 5)$

Explanation:

Step1: Distribuir $3x$ en el trinomio

$3x \cdot 2x^2 + 3x \cdot (-5x) + 3x \cdot (-5)$
$= 6x^3 - 15x^2 - 15x$

Step2: Distribuir $-4$ en el trinomio

$-4 \cdot 2x^2 + (-4) \cdot (-5x) + (-4) \cdot (-5)$
$= -8x^2 + 20x + 20$

Step3: Sumar los resultados obtenidos

$6x^3 - 15x^2 - 15x - 8x^2 + 20x + 20$

Step4: Combinar términos semejantes

$6x^3 + (-15x^2 - 8x^2) + (-15x + 20x) + 20$
$= 6x^3 - 23x^2 + 5x + 20$

Answer:

$6x^3 - 23x^2 + 5x + 20$
