Starting with x%5E2%2Bbx%2Bc=0, and assigning roots as p and q, and working with the roots from use of quadratic formula,

system%28p%2Bq=-b%2Cpq=c%29


If p and q are to be roots for x%5E2%2Bpx%2Bq=0 then this system should be possible:


system%28p%2Bq=-p%2Cpq=q%29

The second of these means p=1; and substituting into the first of these gives a way to solve for q.
highlight%28system%28p=1%2Cq=-2%29%29

1.  Writing by "josgarithmetic" is   W R O N G   F R O M   T H E   B E G I N N I N G   T O   T H E   E N D.


2.  Your writing is also wrong. 

   The correct writing is this:


   If p and q are the roots of x^2+px+q=0, find p and q.

Do you see the difference ?
