Question

Isabella is solving the equation 4x2 = 13x – 3 with the quadratic formula.* What values should she use for a, b, and c?

Answer 1

`ax^2+bx+c=0\\\\4x^2=13x-3\\\\4x^2-13x+3=0\\\\a=4;\ b=-13;\ c=3`

Answer 2

a = 4

b = -13

c = 3

Explanation:

We have been given the equation

`4x^2=13x-3`

Subtract
`4x^2` to both sides of the equation

`0=-4x^2+13x-3`

Multiply both sides of the equation by -1

`4x^2-13x+3=0`

The general equation of a quadratic equation is
`ax^2+bx+c=0`

Comparing this equation with above equation
`4x^2-13x+3=0`

a = 4

b = -13

c = 3
