List the like terms in the following group of terms.

–7u, 4tu2, 4t2u, –5tu2, 7tu2, 6t2
did I do this correct?

(4tu² + 7tu² + -5tu²) + 4t²u +6t² +-7u

It should be...

6t^2 + 4t^2u + 7tu^2 - 7u

how come you don't use the 4tu^2

oh i am sorry...it should be 6tu^2 instead of 7tu^2

sorry about that:)

the -5, 7, and 4 should be combined
