add or subtract. P.s this is a polynomial.

(2x^2 + 6x + 1) + (-7x^2 + 2x - 3)

A. -9x^2 -8x + 2
B. 5x^2 + 8x - 2***
C. 5x^2 - 8x + 2
D. 5x^2 -4x -2

i choose B. check please

-5x^2 + 8x - 2

Do you have a typo?

Yes sorry.

A. -9x^2 - 8x + 2
B. -5x^2 + 8x - 2***
C. 5x^2 -8x + 2
D. 5x^2 -4x - 2
I choose B

To add or subtract polynomials, you need to combine like terms. In this case, you have:

(2x^2 + 6x + 1) + (-7x^2 + 2x - 3)

First, let's combine the like terms:

2x^2 + (-7x^2) = -5x^2
6x + 2x = 8x
1 + (-3) = -2

So, the simplified form of the polynomial is:

-5x^2 + 8x - 2

Comparing this with the answer choices, we can see that the correct answer is B. 5x^2 + 8x - 2. Well done!
