Question

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

Answer 1

Answer:

To find a b and c in a quadratic equation, the x^2 number is a, so 7x^2 is your a value, your b value is just the x, so your b value is -9, and your c value is the regular number, which is 18.  a=7x^2 b=-9x c = 18.  So your answer is answer B.
