Hi mastermin346,

sa-ri-ga-ma's method is a fast way...

the long way to do it is

the equation in form is

One root is

The other root is

The larger root must be the first one if the roots are real.

Then twice the second root is the first.

The equation is

Either find the roots of this or substitute "p" into
