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!
