Question

Are 5x^2 and -9x^2 like terms

true or false

Answer 1

true

Explanation:

when unlike terms are added, they cannot be "combined".

examples of unlike terms:
`2x +3` and
`5y - 2` and
`6y^2 - 4x^2`

`5x^2 and -9x^2` are like terms because they both contain the variable x and have an exponent of 2.
