Quadratic Formula Mastery

Test

Test your understanding of the quadratic formula! In this quiz, you'll be asked to:

Identify coefficients: Determine the values of a, b, and c in a given quadratic equation (ax² + bx + c = 0).
Calculate the discriminant: Use the formula D = b² - 4ac to find the discriminant.
Interpret the discriminant: Determine the number of solutions based on the value of the discriminant.
Apply the quadratic formula: Substitute the values of a, b, and c into the quadratic formula: x = (-b ± √(b² - 4ac)) / (2a).
Solve for x: Simplify the expression and find the solutions to the equation.
Remember:

The discriminant tells you the number of solutions (two, one, or none).
If the discriminant is negative, there are no real solutions.
If the discriminant is zero, there is one real solution (a double root).
If the discriminant is positive, there are two distinct real solutions.
Let's see how well you can master the quadratic formula!
