Do you know what like terms are?

anonymous · Answer

no i have been out of school for 2 years for health issues and i came back and they just threw this at me like i knew how to do it.?

parthkohli · Answer

Okay, like terms are for example:
-> 5y^2 and -2y^2
-> 3x and 4x
-> 5 and 2
-> 3x^3 and 6x^2

They have the numerical coefficients different, but they have the rest of the expression same.
They can be added or subtracted.

okay so watt are you saying? (just curious)

parthkohli · Answer

You have gotta add the like terms together :)
