What are the most common mistakes students make in Quadratic Equations?
a negative discriminant gives two complex conjugate roots, not 'no roots'.
Top mistakes to avoid in Quadratic Equations: • a negative discriminant gives two complex conjugate roots, not 'no roots'. • thinking D<0 means 'no solution'. • dropping the minus sign in −b/a. • solving fully when you only need the nature of the roots.
