We have quadratic equationax^2 + bx + c = 0 (where a, b and c are constants and a>0)
We need to find out what percentage is 'c' greater than |b|(absolute value of b). Also known are the roots of the roots are p andq.

(1) |p+1| = |q–3|
Assume values for p and q which satisfy the equation.
Example 1 : p=+2,q=+5. A quadratic equation can be formed by (x-p)(x-q)
(x-2)(x-5) => x^2 -7x +10 = 0. Here c(10) is around 42.85% greater than |b|, which is 7.
Example 2 : p=+2,q=0. A quadratic equation
