PLEASE HELP For the expression below, write two other equivalent expressions using different terms. Make sure one is fully simplified. -4(x+2)-2x+4

Given:

The given expression is

To find:

The two other equivalent expressions.

Solution:

We have,

Using distributive property, we get

So, one equivalent expression is .

On further simplification, we get

Therefore, the second and fully simplified equivalent expression is .

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
