Identifying the values a, b, and c is the first step in using the Quadratic Formula to find solution(s) to a quadratic equation.

What are the values a, b, and c in the following quadratic equation?

−6x = −8x^2 − 13

A. a = 8, b = −6, c = 13
B. a = −6, b = −8, c = 13
C. a = −6, b = −8, c = −13
D. a = −8, b = −6, c = −13
