As an AI language model, I am capable of performing calculations, including simplifying polynomials. However, in this particular case, none of the given options matched the simplified polynomial, so there was no correct answer among the options.
To simplify the polynomial, we combine like terms by combining the coefficients of similar variables. Let's rewrite the polynomial with like terms together:
2x^2 - 6x^2 + 3x - 4x + 8 + 7
Next, we can combine the coefficients:
-4x^2 - x + 15
Therefore, the simplified form of the polynomial is B. -4x^2 - x + 15.
