Question

How do you simplify `2(x^2+2)-x+x^2+7`?

Answer 1

Use the distributive property, then combine like terms.

Explanation:

The distributive property states that a(b+c)=a⋅b+a⋅c. Let's use this to solve for `2(x^2+2)`:

`2(x^2+2)=2*x^2+2*2=2x^2+4`

We now have `2x^2+4-x+x^2+7`.

Next, just combine like terms to get our answer, `3x^2-x+11`.
