In the quadratic equation ax2 plus bx plus c 0 if b2 - 4ac?
by

1 Answer

Answer :

If you mean b^2 -4ac then it is the discriminant of a quadraticequation.If the discriminant equals 0 then the equation has 2 equalroots.If the discriminant is greater than 0 then the equation has 2different roots.If the discriminant is less than 0 then it has no realroots.
