Answer:
[tex]10x^2+7x[/tex]
Step-by-step explanation:
First let's identify the two terms: [tex]x^{2}[/tex] and [tex]x[/tex].
The equation isn't combined or simplified rather. To simplify/combine like terms, you add/subtract the identical terms together. So let's do just that.
[tex]8x^2+2x^2+7x\\10x^2+7x[/tex]
Your final answer is : [tex]10x^2+7x[/tex]
