Answer:−2x^3+8x^2−4x

Explanation:

Equation:-2x(x2-4x+2)

=(−2x)(x^2+−4x+2)

=(−2x)(x^2)+(−2x)(−4x)+(−2x)(2)

=-2x^3+8x^2-4x

In this question, we would be using the distributive property to solve the expression.

Solve by distributing and combining any like terms at the end.

Solve:

-2x(x² - 4x + 2)

Distribute the -2x to each part in the parenthesis.

-2x(x² - 4x + 2)

-2x³ + 8x² - 4x

Since there is no like terms in the final expression, you would just leave it as is.
