Question

How do you simplify `(x^2 + 2x + 3) + (x^2 - 5)`?

Answer 1

`2x^2 + 2x - 2`

Explanation:

To simplify this expression, we need to combine like terms, or the terms that share a common variable or lack thereof in the case of `3` and -`5`:

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

Note that the exponent of the variable must match as well as the variable itself in order to be considered a like term.
