Question

Using Fortran obtain the root of quadratic question ax^2+6x+c=0

Answer 1

FORTRAN? do you use it yet? :-0

Answer 2

You can't solve, unless a & c values are given. Write program to solve x = (-b +/-√(b2 - 4ac))/2a, where b is the 6. You should end up with two numbers for x, which both work in quadratic equation.
