How to fill out lesson 9 solving quadratic

How to fill out Lesson 9 solving quadratic?

1. Start by understanding the concept of quadratic equations. Quadratic equations are algebraic expressions that contain a variable raised to the power of 2, such as ax^2 + bx + c = 0.
2. Review the formulas and methods involved in solving quadratic equations. The most commonly used methods are factoring, using the quadratic formula, and completing the square.
3. Read and analyze the problem given in Lesson 9. Identify the quadratic equation that needs to be solved and determine the values of the coefficients (a, b, and c).
4. Choose the most appropriate method to solve the quadratic equation based on the given problem. Consider factors such as simplicity, time constraints, and personal preference.
5. If the equation can be factored, use the factoring method. Break down the quadratic equation into two binomial factors in the form (x - r)(x - s) = 0, where r and s are the roots of the equation.
6. If factoring is not feasible or does not work, use the quadratic formula. The quadratic formula is x = (-b ± √(b^2 - 4ac))/(2a). Substitute the values of the coefficients into the formula and solve for x.
7. If the quadratic equation cannot be factored and the quadratic formula seems too complex, consider using the method of completing the square. Transform the equation into a perfect square trinomial and solve for x.
8. Double-check your solution to ensure accuracy. Plug the obtained values of x back into the original quadratic equation and verify that it satisfies the equation.
