Help ASAP! Algebra 2 question! What is the product?

Answer 1

First option:
`-10d^4+17d^2s-6s^2`

Explanation:

`\left(-2d^2+s\right)\left(5d^2-6s\right)`

Use FOIL method to expand:
`\left(a+b\right)\left(c+d\right)=ac+ad+bc+bd`

`\left(-2d^2\right)* 5d^2+\left(-2d^2\right)\left(-6s\right)+s* 5d^2+s\left(-6s\right)`

`-2*5d^2d^2+2* 6d^2s+5d^2s-6s^2`

`-10d^4+12d^2s+5d^2s-6s^2`

`-10d^4+17d^2s-6s^2`
