Question

V(x)=-x2+2x-4 and W(x)=-x3+2x2+x+5 Find V(x)-W(x)

Answer 1

`x^(3) -3x^(2) +x-9`

Explanation:

-x^2+2x-4-(-x^3+2x^2+x+5)

Combine like terms

x^3-3x^2+x-9

Answer 2

`-x^3-x^2+x-9`

Explanation:

Distribute -1

Combine Like Terms

`(x^2+2x-4)-(x^3+2x^2+x+5)\\= x^2+2x-4+-x^3-2x-x-5\\= -x^3-x^2+x-9`
