Question

How do you evaluate `-2h ^ { 2} ( 3h ^ { 2} - 4h - 3)`?

Answer 1

`-6h^4+8h^3+6h^2`

Explanation:

Remember this rule:
`a(b+c+d)=ab+ac+ad`
Basically, it's a bit longer process of distrubtive property.

Therefore, `-2h^2(3h^2-4h-3)=-2h^2xx3h^2+(-2h^2)xx-4h+(-2h^2)xx-3`
This is equal to `-6h^4+8h^3+6h^2`
