- Given ax2 + bx + c = 0,We know sum of roots= -b/a and product of roots=c/a
Therefore according to the given question -b/a=c/a
and given sum of equal roots ,Let w be equal root then 2w=-b/a & w2=c/a
on solving we get discriminant(b2-4ac=0) and a=0 is the answer - 11 years agoHelpfull: Yes(2) No(9)
