LET’S BREAK IT DOWN
Start with an example.
The quadratic formula is x = (−b ± √(b² − 4ac)) / (2a). For x² − 5x + 6 = 0, the discriminant is 1, and the roots are 2 and 3.
KEEP IN MINDThe discriminant b² − 4ac indicates the type of roots: positive gives two distinct real roots, zero gives a repeated real root, and negative gives complex conjugate roots.
