Question

Simplify the expression by combining like terms
13x^2-7x^2-15

Answer 1

Answer:
`6x^2-15`

Explanation:

Here is what we are given :
`13x^2-7x^2-15` and we must simplify.

We can notice that the
`13x^2` and
`7x^2` are in like terms so we can combine them.

Since
`7x^2` is negative, we must subtract is from
`13x^2` and we get
`6x^2`. The
`-15` stays unchaned because there are no other constant values.

That's it!
