Question

expand the expression to a polynomial in standard form:
$(4x + 5)(x^2 - 2x + 5)$

Explanation:

Step1: Distribuir $4x$ en el trinomio

$4x(x^2 - 2x + 5) = 4x^3 - 8x^2 + 20x$

Step2: Distribuir $5$ en el trinomio

$5(x^2 - 2x + 5) = 5x^2 - 10x + 25$

Step3: Sumar los resultados anteriores

$(4x^3 - 8x^2 + 20x) + (5x^2 - 10x + 25)$

Step4: Combinar términos semejantes

$4x^3 + (-8x^2 + 5x^2) + (20x - 10x) + 25 = 4x^3 - 3x^2 + 10x + 25$

Answer:

$4x^3 - 3x^2 + 10x + 25$
