Roots of quadratic equation is equal, so,
Put the value of a, b and c in the formula and prove a/b=c/d...
OK... OK... I will do it...

see... D = b2-4ac... we calculate D for checking the nature of roots
if D<0... roots are imaginary
Hmm ryt...thnk u
if D>0... roots are real and unequal
here Roots were equal so D = b2-4ac
that means D is 0
b2-4ac =0
b2=4ac
please follow me
