To determine the nature of roots of quadratic equations (in the form ax^2 + bx +c=0) , we need to calculate the discriminant, which is b^2 – 4 a c. When the discriminant is greater than zero, the roots are unequal and real. When the discriminant is equal to zero, the roots are equal and real. When the discriminant is less than zero, the roots are imaginary.
