I was wondering how you add these two equations together (4 {x}^(2) - 2x) + (5x - 7)

Question

I was wondering how you add these two equations together
`(4 {x}^(2) - 2x) + (5x - 7)`

Answer 1

Explanation

We are given the following:

`(4x^2-2x)+(5x-7)`

We are required to simplify the expression above.

This is achieved thus:

`\begin{gathered} (4x^(2)-2x)+(5x-7) \\ \text{ Remove the brackets} \\ 4x^2-2x+5x-7 \\ =4x^2+3x-7 \end{gathered}`

Hence, the answer is:

`\begin{equation*} 4x^2+3x-7 \end{equation*}`
