Question

2x^2+2 + 3x^2- 1
I’m trying to combine like terms plz help

Answer 1

5x²-1

Explanation:

We are given the expression:

`2x^2+2 + 3x^2- 1`

and asked to simplify.

To simplify this expression, we must combine like terms.

2x²⇒ this has a variable, x²

2⇒ no variable

3x²⇒this has a variable, x²

-1⇒ no variable

Group the like terms.

`(2x^2 + 3x^2)+(- 1+2)`

Add 2x² and 3x². Add the coefficients and add an x² on the end.

`(2+3)x^2+(-1+2)`

`(5)x^2+(-1+2)`

`5x^2+(-1+2)`

Combine -1 and 2.

`5x^2+(-1)`

`5x^2-1`

The expression 2x²+2+3x²-1 simplified is 5x²-1

Answer 2

5x^2+1

Explanation:

2x^2 and 3x^2 are like terms so just add them which gives 5x^2.

2 and -1 are like terms so combine them to make 1.
