Question

Simplify the equation​

Answer 1

`D.`
`6x^3 + 14x^2 +2x - 6`

Explanation:

(2x +2)(3x^2 + 4x - 3)

Simplify

__________________

We are given one binomial and one polynomial and are asked to simplify it.

To solve, all we need to do is follow the FOIL rule :

First

Outer

Inner

Last

`(2x + 2)(3x^2 + 4x - 3)`

`2x * 3x^2`

`6x^3`

`2x*4x`

`6x^3 + 8x^2`

`2x*-3`

`6x^3 + 8x^2 - 6x`

Now go for 2 in the first bracket :

`2*3x^2`

`6x^3 + 8x^2 - 6x + 6x^2`

`2*4x`

`6x^3 + 8x^2 - 6x + 6x^2 + 8x`

`2 * -3`

`6x^3 + 8x^2 - 6x + 6x^2 + 8x - 6`

Combine like terms :

`6x^3 + 14x^2 +2x - 6`

Answer 2

Answer D 6x^3+14x^2+2x-6
