Question

How do you combine like terms in `(4x ^ { 4} + 5x ^ { 3} - 17x ^ { 2} - 15x ) + ( - 3x ^ { 3} + 3x ^ { 2} - 3)`?

Answer 1

`4x^4+2x^3-14x^2-15x-3`

Explanation:

Adding the like terms, e.g. `ax^4+bx^4+ax^3+bx^3+ax^2+bx^2...`
`(4x^4+5x^3-17x^2-15x)+(-3x^3+3x^2-3)`
`4x^4+(5x^3-3x^3)+(-17x^2+3x^2)-15x-3`
`4x^4+2x^3-14x^2-15x-3`
