Question

Determine the value of a, b, and c for the quadratic equation: 4x2- 8x = 3

A) a=4, b=-8, c=3

B) a=4, b=-8, c=-3

C) a=4, b=8 ,c=3

D) a=4, b=8, c=-3

Answer 1

B. a = 4, b = -8, c = -3

Explanation:

The quadratic equation given is:

`4x^2- 8x = 3`

The general form of a quadratic equation is given as:

`ax^2 + bx +c = 0`

Let us put the given equation in this form and then compare with the general form of the quadratic equation.

`4x^2- 8x = 3\\\\4x^2 - 8x - 3 = 0`

Therefore, by comparing:

a = 4

b = -8

c = -3

The correct option is B
