How to fill out pre-calculus completing form square

How to fill out pre-calculus completing the square:

1. Begin by identifying the quadratic equation that needs to be completed. This equation should be in the form of ax^2 + bx + c = 0.
2. Make sure that the coefficient of the x^2 term (a) is equal to 1. If it is not, divide the entire equation by 'a' to make it equal to 1.
3. Move the constant term (c) to the other side of the equation, changing its sign. This will result in the equation being in the form of x^2 + bx = -c.
4. Take half of the coefficient of the x term (b/2) and square it. Add this value to both sides of the equation. This step is crucial in completing the square.
5. Rewrite the left side of the equation as a perfect square trinomial. The equation should now be in the form of (x + b/2)^2 = -c + (b/2)^2.
6. Simplify the right side of the equation, if needed.
7. Solve for 'x' by taking the square root of both sides of the equation. Don't forget to consider both positive and negative square roots.
8. Finally, simplify the solution(s) obtained in the previous step to obtain the values of 'x' that satisfy the quadratic equation.
