Finding the Roots of the Quadratic Equation
The quadratic formula is used to find the roots of a quadratic equation. The quadratic equation must be in the form . The terms in must be in the exact order shown. The quadratic formula is . Move sliders , or . Slider is the coefficient in the term . Slider is the coefficient in the term . Slider is the constant term (also the coefficient in the term ). When the quadratic intersects the -axis, the quadratic has real number roots. Real numbers roots can happen in two ways. A quadratic intersect the -axis at two points, or a quadratic intersects the -axis at one point. When the quadratic does not intersect the -axis, the quadratic has imaginary number roots.
