What is the nature of zeros in quadratic function?
Nature Of The Zeros Of A Quadratic Function
The quantity b2_4ac that appears under the radical sign in the
quadratic formula is called the discriminant.It is also named
because it discriminates between quadratic functions that have real
zeros and those that do not have.Evaluating the discriminant will
determine whether the quadratic function has real zeros or not.
The zeros of the quadratic function f(x)=ax2+bx+c can be
expressed in the form
S1= -b+square root of D over 2a and S2= -b-square root of D over
2a, where D=b24ac....
hope it helps... :p
sorry for the square root! i know it looks like a table or
something...
