How do you combine like terms in (- 5t ^ { 2} + 4t - 3) + ( 7t ^ { 2} + t + 6)?

2t^2+5t+3

Explanation:

Collect up like terms for this expression.

Those brackets do not mean anything in this case since the only operations are subtraction and multiplication.

-5t^2+7t^2+4t+t-3+6
=2t^2+5t+3

Always perform the operations when they are the same, do not collect up like terms when they are not alike.
e.g
4t^2+t
You cannot add them together since the pronumeral isn't the same.
