Question

Simplify the expression
6t^2-5.4-3.5+2.5t^2+3t

Answer 1

6t^2 - 5.4 - 3.5 + 2.5t^2 + 3t

basically, all we have to do is combine like terms. Do you know what like terms are ?

Answer 2

yes

Answer 3

example : like terms
5 + 4 = 9
6t + 4t = 10t
3x^2 + 4x^2 = 7x^2

unlike terms
5 + 2t
6 - 3t^3
4t^2 + 7t

Answer 4

so put your like terms together..
6t^2 + 2.5t^2 = ??
-5.4 - 3.5 = ??
and don't forget about 3t...even though it does not have any like terms
