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?
18 = −9x + 7x2
a = 18, b = 9, c = −7
a = 18, b = −9, c = 7
a = 7, b = 9, c = 18
a = −7, b = 9, c = 18
The correct values of a, b, and c are:
a = 7, b = -9, c = 18
