How to fill out solving quadratics by completing

How to fill out solving quadratics by completing?

1. Start by identifying the quadratic equation that needs to be solved. It should be in the form of ax^2 + bx + c = 0.
2. If the coefficient 'a' is not 1, divide the entire equation by 'a' to make it easier to work with.
3. Next, ensure that the quadratic equation is in standard form, that is, the terms are arranged in descending powers of x.
4. Identify the values of 'a', 'b', and 'c' in the quadratic equation.
5. If necessary, rearrange the equation so that the constant term 'c' is isolated on one side of the equation, and the rest of the terms are on the other side.
6. Once the equation is in standard form and the constant term is isolated, it's time to complete the square.
7. Take half of the coefficient of 'b', square it, and add that value to both sides of the equation. This step ensures that the quadratic equation can be factored into a perfect square.
8. On one side of the equation, you should have a perfect square trinomial. Factor it, and rewrite the equation in factored form.
9. Solve for x by setting each factor equal to zero and finding the corresponding values for x. This will give you a set of possible solutions.
10. Check all the solutions by substituting them back into the original equation. Ensure that both sides of the equation are equal when the solutions are plugged in.
