question
expand the expression to a polynomial in standard form:
(-2x + 1)(x² - 9x + 10)

Explanation:

Step1: Distribuir $-2x$ en el trinomio

$-2x \cdot x^2 + (-2x) \cdot (-9x) + (-2x) \cdot 10 = -2x^3 + 18x^2 - 20x$

Step2: Distribuir $1$ en el trinomio

$1 \cdot x^2 + 1 \cdot (-9x) + 1 \cdot 10 = x^2 - 9x + 10$

Step3: Sumar los resultados y combinar términos semejantes

$(-2x^3 + 18x^2 - 20x) + (x^2 - 9x + 10) = -2x^3 + (18x^2 + x^2) + (-20x - 9x) + 10$
$= -2x^3 + 19x^2 - 29x + 10$

Answer:

$-2x^3 + 19x^2 - 29x + 10$
