Quadratic equation, Mathematics

If roots of (x-p)(x-q) = c are a and b

what will be the roots of (x-a)(x-b) = -c please explain.

Solution)  (x-p)(x-q)=c


hence,   a+b=p+q

 and    a.b=pq-c


by solving other eq we get


thus  sum of roots=a+b=p+q

 product of roots=a.b+c=p.q

hence its roots are pand q
