Guided Notes

3 key concepts

  • 1

    The quadratic formula can be used to solve quadratic equations in the form of Ax² + Bx + C = 0, where A ≠ 0.

  • 2

    The quadratic formula is x = (-B ± √(B² - 4AC)) / 2A.

  • 3

    If the discriminant (B² - 4AC) is negative, the quadratic equation has no real solutions.
