Question

How do you combine like terms in `(6x ^ { 2} - 5x ) - ( 4x ^ { 2} - 3x + 4)`?

Answer 1

`2x^2-2x-4`

Explanation:

First distribute the negative on the second parentheses term:
`(6x^2-5x)-(4x^2-3x+4)`

`=6x^2-5x-4x^2+3x-4`

Group like terms together:
`=(6x^2-4x^2)+(-5x+3x)+(-4)`
`=2x^2-2x-4`
