Question

Find the difference and simplify your answer (5t^2 + 2t - 4 ) - (5t^2 - 2t - 3 )

Answer 1

To find the difference, you can follow the steps above:

1) Evaluate if you can solve the expressions inside the parentheses.

Since there is nothing to solve inside the parentheses, we can move in.

2) Remove the parentheses (do not forget the external signs).

`5t^2+2t-4-5t^2+2t+3`

3) Organize the variables putting the same variables together.

`5t^2-5t^2+2t+2t-4+3`

4) Sum the corresponding variables.

`\begin{gathered} 0+4t+1 \\ 4t+1 \end{gathered}`

So, the answer is:

`4t+1`
