Discriminant (D):

D = b² - 4ac

If D > 0  → Two distinct real roots
If D = 0  → Two equal real roots (repeated root)
If D < 0  → No real roots (complex roots)

Sum and Product of Roots:

Sum of roots (α + β) = -b/a
Product of roots (αβ) = c/a

Forming Equation from Roots:

x² - (sum of roots)x + (product of roots) = 0
