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? −6x2 − 8x + 12
a = −6, b = −8, c = 12
a = 6, b = 8, c = 12
a = 8, b = 12, c = 0
a = −8, b = 12, c = 0

Answer 1

I hope it helps you get it right

Answer 2

Answer:

Option A.

Step-by-step explanation:

If a quadratic equation is defined as  

$ax^2+bx+c=0$          ....(i)

then the quadratic formula is

$x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

Consider the given quadratic equation is  

$-6x^2-8x+12=0$          ....(ii)

On comparing (i) and (ii), we get

$a=-6,b=-8, c=12$

Hence, the correct option is A.
