Question

Factor –8x3 – 2x2 – 12x – 3 by grouping. What is the resulting expression?

Answer 1

The answer is (-4x-1)(2x^2+3) when factoring this expression by grouping

Answer 2

The resulting expression is
`(4x+1)(-2x^2-3)`

Explanation:

Consider the provided expression.

`-8x^3-2x^2-12x-3`

The above expression can be written as:

`(-8x^3-2x^2)+(-12x-3)`

Take out the greatest common factor from each group.

`-2x^2(4x+1)-3(4x+1)`

Further solve the above expression.

`(4x+1)(-2x^2-3)`

Hence, the required expression is

`(4x+1)(-2x^2-3)`

The resulting expression is
`(4x+1)(-2x^2-3)`
