Quadratic Formula

x = (-b ± √(b² - 4ac)) / (2a)

Discriminant (b² - 4ac):

• Positive: Two real solutions

• Zero: One real solution

• Negative: Two complex solutions

Algebra Tips

Always check your solutions by substituting back into the original equation.

The vertex of a parabola is at x = -b/(2a).

For factoring, look for common factors first before using the quadratic formula.

Complex solutions occur when the discriminant is negative.
