Quadratics: Vertex to Standard Form

This video tutorial from MooMooMath covers the process of converting a quadratic equation from vertex form to standard form. It begins with an introduction to quadratics and the vertex form, followed by a step-by-step explanation of how to apply algebraic skills to expand and simplify the equation. The tutorial demonstrates distributing coefficients and combining like terms to arrive at the standard form of the quadratic equation. The final result is presented with the coefficients identified, providing a clear understanding of the conversion process.
