This lesson guides students through deriving the Quadratic Formula from a quadratic equation, using it to solve problems, and analyzing common student errors. It connects the formula to graphical representations and defines the discriminant to identify the number of real roots.

How to fill out quadratic formula lesson

How to fill out quadratic formula lesson

1. Identify the coefficients a, b, and c in the quadratic equation of the form ax^2 + bx + c = 0.
2. Write down the quadratic formula: x = (-b ± √(b² - 4ac)) / (2a).
3. Calculate the discriminant (b² - 4ac) to determine the nature of the roots.
4. If the discriminant is positive, there are two real and distinct solutions.
5. If the discriminant is zero, there is one real solution (a repeated root).
6. If the discriminant is negative, there are no real solutions (but two complex solutions).
7. Plug the values of a, b, and c into the formula to find the values of x.
8. Simplify the equation to express the solutions clearly.
