Only add like terms.

Explanation:

Terms must have exactly the same variables - and the same order of variables before they can be added. Look for like terms .

For example, #color(blue)x - color(red)(3x^2) - color(orange)(5x^3) + color(blue)(2x) + color(red)(7x^2) - color(orange)(4x^3)#

The like terms are shown in the same colours.

=# color(blue)(3x) +color(red)(4x^2) - color(orange)(9x^3)#
