Common mistakes
- ⚠️ Not checking if zu=0 (would make it linear, not quadratic)
- ⚠️ Forgetting the ± gives two solutions, not just one
- ⚠️ Misapplying signs when b is negative in the formula
Worked example
Solve the quadratic equation 2x² + 7x + 3 = 0 using the quadratic formula
The solutions x1 ({x1}) and x2 ({x2}) are the roots where the parabola crosses the x-axis; discriminante ({discriminante}) determines solution type (positive=2 real, zero=1 real, negative=complex)
