In this case, you need to set the equation equal to zero before you can identify the values for a, b, and c.
So, the equation becomes:
7x^2 + 2x - 4 = 0
Now you can identify a=7, b=2, and c=-4.
ou are solving a quadratic by using the Quadric Formula, What needs to be done to this function before we can identify a, b, and c? 7x^2 + 2x =4
The quadratic first needs to be factored.
The like terms need to be combined.
The equation needs to be set to zero.
We need to add 4 on both sides of the equation.
