Quadratic Polynomial
A quadratic polynomial in a variable xx is an equation which is of the form p(x) = ax^2 + bx + c = 0p(x)=ax
2
+bx+c=0 where constants aa , bb and cc are all real numbers and a \neq 0a
=0 .
Let us consider a quadratic polynomial ax^2 + bx + c = 0ax
2
+bx+c=0 , then nature of roots of quadratic polynomial depends upon Discriminant D = b^2 - 4acD=b
2
−4ac of the quadratic polynomial.
If D = b^2 - 4ac > 0D=b
2
−4ac>0 , then roots of the equation are real and unequal.
So our final answer is :
If the discriminant of a quadratic polynomial, D > 0, then the polynomial has two real and unequal roots.

−4ac of the quadratic polynomial.
where the expression b^2 - 4acb
2
−4ac is called the discriminant.
If D = b^2 - 4ac > 0D=b
2
−4ac>0 , then roots of the equation are real and unequal.
If D = b^2 - 4ac = 0D=b
2
−4ac=0 , then roots of the equation are real and equal.
If D = b^2 - 4ac < 0D=b
2
−4ac<0 , then roots of the equation are unreal or complex or imaginary.
