Converting Quadratic Functions: Standard to Vertex Form

This video tutorial by Mario from Mario's Math Tutoring explains how to convert quadratic equations from standard form to vertex form by completing the square. The lesson includes three examples: a simple quadratic with a leading coefficient of 1, a more challenging quadratic with an integer leading coefficient, and a complex quadratic with a negative fractional leading coefficient. Mario provides step-by-step instructions and tips to help students understand the process and apply it to different types of quadratic equations.

What is the first step in converting a quadratic equation from standard form to vertex form?

• Divide both sides by the leading coefficient

• Multiply both sides by the leading coefficient

• Add the constant term to both sides

• Subtract the constant term from both sides

In the first example, what value is added to both sides to complete the square?

• 8

• 6

• 17

• 9
