Since “a” and “ma” are roots of , then we can say that:

      Sum of roots = a + ma

Also, sum of roots also = 

Therefore, a + ma = - p 

a(1 + m) = - p

 ------ eq (i)



Product of roots = 

Product of roots also = 

Therefore, 

 ------ eq (ii)

 -------- Substituting  for a in eq (ii)



 ------- Cross-multiplying
