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? −5x2 − 9x + 12 = 0
A: a = −9, b = 12, c = 0
B: a = −5, b = −9, c = 12
C:a = 5, b = 9, c = 12
D:a = 9, b = 12, c = 0

Answer 1

Answer:

So, the answer is option B: a = −5, b = −9, c = 12

Step-by-step explanation:

The general form of the quadratic Formula is  ax² + bx + c = 0

We need to compare the given quadratic equation to the general form

 ax² + bx + c = 0

−5x² − 9x + 12 = 0

So, we can deduce that

a = -5 , b = -9 and c = 12

So, the answer is option B: a = −5, b = −9, c = 12
