🎬 Video Tutorial

(0:23) The Discriminant: The term $b^2 – 4ac$. A positive discriminant means two real roots, zero means one root, and a negative value means no real roots.
(0:58) Step-by-Step Examples: Identifying coefficients ($a$, $b$, $c$), substituting them into the quadratic formula, $x = \small \large \frac{-b \pm \sqrt{b^2 – 4ac}}{2a}$, and calculating the solutions.
