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

5x²-1

Step-by-step explanation:

We are given the expression:

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.

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

Combine -1 and 2.

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

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
