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? −3x2 − 5x + 9 = 0 a = 5, b = 9, c = 0 a = 3, b = 5, c = 9 a = −3, b = −5, c = 9 a = −5, b = 9, c = 0

Answer 1

a = -3, b = -5 and c = 9

Explanation:

Given Quadratic Equation is:

=>
`-3x^2-5x+9`

Comparing it with standard form of quadratic equation
`ax^2+bx+c`, we get

=> a = -3, b = -5 and c = 9

Answer 2

a = -3 b = -5 and c = 9

Explanation:

−3x^2 − 5x + 9 = 0

The quadratic function is written as

ax^2 + bx+c =0

So a = -3 b = -5 and c = 9
