How to fill out 9-4 solving quadratic equations

How to fill out 9-4 solving quadratic equations:

1. Identify the quadratic equation: The first step is to determine if the equation you are working with is quadratic. Quadratic equations have a general form of ax^2 + bx + c = 0, where a, b, and c are constants and x represents the variable.
2. Rearrange the equation: If the equation is already in the form ax^2 + bx + c = 0, then proceed to the next step. Otherwise, rearrange the equation to get it in this form. This may involve moving terms around, combining like terms, or isolating the variable on one side of the equation.
3. Identify the values of a, b, and c: Once the equation is in the standard form, identify the values of the coefficients a, b, and c. These values will be used in the subsequent steps to solve the equation.
4. Apply the quadratic formula: The quadratic formula is given by x = (-b ± √(b^2 - 4ac)) / (2a). Plug in the values of a, b, and c into the formula and simplify the expression. This will give you the values of x that satisfy the quadratic equation.
5. Solve for x: Depending on the discriminant (b^2 - 4ac), there can be three possibilities: two distinct real roots, one repeated real root, or two complex conjugate roots. Calculate the discriminant and determine the nature of the solutions accordingly.
