Explanation:
Quadratic equations are in the form
In your equation, the "a" is actually the "x" term in the quadratic equation form because it is the sole variable in your equation. Thus, to avoid confusion, we can rewrite the equation as
The a, b, and c values for your equation are 1, -28, and 192, respectively. (
Now plug the numbers in to solve:
Thus your answers are a=16, a=12
