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...

What is Nature of the zeros of a quadratic function?
If you have a quadratic function with real coefficients then it can have: two distinct real roots, or a real double root (two coincidental roots), or no real roots. In the last case, it has two complex roots which are conjugates of one another.
What is the quadratic function for the zeros -4 and -4?

What is a quadratic polynomial which has no zeros?
A quadratic polynomial must have zeros, though they may be complex numbers.A quadratic polynomial with no real zeros is one whose discriminant b2-4ac is negative. Such a polynomial has no special name.
Formula for finding zeros of polynomial function?
Try the quadratic formula. X = -b ± (sqrt(b^2-4ac)/2a)
What is the degree of a quadratic function?
A quadratic function will have a degree of two.
