Question

Solve (8u^2+3u-4)+8u^2+3u-1)-(3u^2-3u-8)

Answer 1

The given expression is

`(8u^2+3u-4)+(8u^2+3u-1)-(3u^2-3u-8)`

First, we use the distributive property

`8u^2+3u-4+8u^2+3u-1-3u^2+3u+8`

Second, we reduce like terms

`\begin{gathered} 8u^2+8u^2-3u^2+3u+3u+3u-4-1+8 \\ 13u^2+9u+3 \end{gathered}`

Hence, the final expression is

`13u^2+9u+3`
