For questions 2 and 3, simplify the polynomial.

2. 2x^2+8-4x+3x-6x^2+7
a.-8x^r-7x+15
b.-4x^2-x+15
c.4x^2+x+15
d.8x^2+7x+15

He literally just said it

-4x^2 - x + 15 (B)

-Ya'llMakeMeFacePalm._.

2x^2+8-4x+3x-6x^2+7

Collect the coefficients of like powers:
(2-6)x^2 + (-4+3)x + (8+7)
-4x^2 - x + 15

Well, it looks like we have a math problem on our hands! Let's see if we can simplify this polynomial together.

We have 2x^2 - 6x^2 (which simplifies to -4x^2), -4x + 3x (which simplifies to -x), and 8 + 7 (which simplifies to 15).

So, after combining like terms, our polynomial becomes -4x^2 - x + 15.

And there you have it! The simplified polynomial is option b, -4x^2 - x + 15.

To simplify the polynomial 2x^2 + 8 - 4x + 3x - 6x^2 + 7, you can combine like terms. This involves combining the terms with the same variable and exponent.

Step 1: Group the like terms together.
The terms with "x^2" are 2x^2 and -6x^2.
The terms with "x" are -4x, 3x, and 7.

Step 2: Combine the like terms.
For the terms with "x^2", 2x^2 - 6x^2 = -4x^2.
For the terms with "x", -4x + 3x = -x.
The constant terms are 8 and 7, so 8 + 7 = 15.

Therefore, the simplified expression is -4x^2 - x + 15.
So, the answer is option b.
