Roots Of A Quadratic Equation
Muhtasari
Every quadratic equation can be solved with a single formula, but the real power lies in knowing what kind of answer to expect before you even start solving. The discriminant tells you at a glance whether an equation has two distinct roots, one repeated root, or no real roots at all.
In this topic you will master the quadratic formula and learn to use the discriminant to classify the roots of any quadratic. You will also see how the discriminant connects to the shape of a parabola and tackle problems where the nature of the roots depends on an unknown parameter.
Malengo
- Use the quadratic formula to solve quadratic equations
- Use the discriminant to identify whether the roots are equal real, unequal real or not real
