Learn how to solve for undetermined coefficients in Quadratic Equations 

Key Points

The discriminant tells us whether a quadratic equation will have 0, 1 or 2 real roots (solutions)

The terms ‘solutions’ and ‘roots’ are often used interchangeably

The discriminant rules work both ‘left to right’ and ‘right to left’

In finding undetermined coefficients we use the discriminant rules ‘right to left’

The terms ‘solution’, ‘solutions (plural)’ and ‘range of solutions’ indicate how your answer should look
