To simplify the polynomial 2x^2 + 8 - 4x + 3x - 6x^2 + 7, you can combine like terms.

First, let's combine the x^2 terms:
2x^2 - 6x^2 = -4x^2

Next, let's combine the x terms:
-4x + 3x = -x

Finally, let's combine the constant terms:
8 + 7 = 15

Putting it all together, the simplified polynomial is:
-4x^2 - x + 15
