Lesson 6: Quadratic Formula and the Discriminant

### VOCAB

• Quadratic Formula – is a formula that will give you the x-intercepts to ANY quadratic equation

• Discriminant – tells you how many real solutions a quadratic equation has (how many times the graph crosses the x-axis)

• 2 is when the discriminant is greater than 0

• 1 is when the discriminant is 0

• 0 is when the discriminant is less than 0

• Set the equation to be equal to zero

• Move everything to one side

• Combine Like Terms

• Plug a, b, and c into the formula

• Solve
