How to fill out quadratic formula amp discriminant

How to fill out quadratic formula amp discriminant

1. To fill out the quadratic formula, follow these steps:
2. Identify the values of 'a', 'b', and 'c' in the quadratic equation: ax^2 + bx + c = 0.
3. Calculate the discriminant using the formula: D = b^2 - 4ac.
4. Determine the nature of the roots based on the value of the discriminant:
5. - If D > 0, the quadratic equation has two distinct real roots.
6. - If D = 0, the quadratic equation has one real root (also called a double root).
7. - If D < 0, the quadratic equation has no real roots (only complex roots).
8. Use the quadratic formula to find the roots:
9. - If the discriminant is positive (D > 0), the roots can be found using the formula:
10. x = (-b ± √D) / (2a)
11. - If the discriminant is zero (D = 0), the formula changes slightly:
12. x = -b / (2a)
13. - If the discriminant is negative (D < 0), the equation has no real roots.
14. Solve for 'x' using the values obtained in step 4. These will be the roots of the quadratic equation.
