Question

Simplify The expressions. All answers should be in standard form.
`{3x}^(2) + 5x - 9x + 2`

Answer 1

We are given the following expression

`3x^2+5x-9x+2`

Let us simplify the above expression

`\begin{gathered} 3x^2+5x-9x+2 \\ 3x^2-4x+2 \end{gathered}`

As you can see, the sum of the terms 5x and -9x is equal to -4x

Therefore, the simplified expression is
