Answer 1

On Edge, the answer is D. 31x2 – 2.

Answer 2

`-12x^4-11x^2-2`

Step-by-step explanation:

Step 1 - Expand

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

`-12x^4-3x^2-8x^2-2`

Step 2 - Combine like terms

`-12x^4-3x^2-8x^2-2`

`-12x^4-11x^2-2`

Therefore, the expression that is equal to
`(-3x^2-2)(4x^2+1)` is
`-12x^4-11x^2-2`.
