Calculus – Quadratic Equations Practice Set · 2

This lesson demonstrates how to apply the quadratic formula to solve a quadratic equation with integer coefficients. Students learn to identify coefficients, compute the discriminant, and simplify both roots. Verification of each solution by substitution is also covered.

In this lesson, you will learn to:
• Identify the coefficients a, b, and c from a quadratic equation in standard form
• Calculate the discriminant and use it to determine the nature and number of solutions
• Apply the quadratic formula to find both roots of a quadratic equation
• Verify solutions by substituting them back into the original equation
