Question

Which polynomial represents the sum: `(14x^2-14)+(-10x^2-10x+10)`?

Answer 1

`4x^2-10x-4`

Explanation:

Note that I have used the place keeper of `0x` in the second line. This represents that there are not any `x` terms

`-10x^2-10x+10`
`ul(color(white)(..)14x^2+color(white)(1)0x-14) larr" Add"`
`" "color(white)(.)4x^2-10x-4`
