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

Answer:a = −6, b = −8, c = 12

Explanation:

Answer 2

Option A.

Explanation:

If a quadratic equation is defined as

`ax^2+bx+c=0` ....(i)

then the quadratic formula is

`x=(-b\pm √(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.
