Question

Combine like terms and write each expression in standard form

Answer 1

From the expression

`x^2-5+2x+x^2`

combining like terms we have to bring the x-squares together, we have

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

To write in standard form, the 2x should come before the -5, so we have

`2x^2+2x-5`

Hence the answer is

`2x^2+2x-5`
