How to fill out solving quadratics by completing

How to fill out solving quadratics by completing:

1. Begin by looking at the quadratic equation in the standard form, ax^2 + bx + c = 0, where a, b, and c are coefficients.
2. Determine the value of a, which is the coefficient of x^2. This value is crucial for solving the quadratic equation by completing the square method.
3. Divide the entire equation by the coefficient of x^2 (a). This step ensures that the coefficient of x^2 becomes 1.
4. Rearrange the equation so that the terms involving x are on one side and the constant term is on the other side.
5. Compute half of the coefficient of x (b/2) and square it [(b/2)^2]. This value will be used to complete the square.
6. Add and subtract the squared value ([(b/2)^2]) to the side of the equation that contains the x terms.
7. Factor the quadratic expression on the left side of the equation (if possible). This may involve using the difference of squares formula or other factoring techniques.
8. Simplify the equation, combining like terms if necessary.
9. Solve for x by using the square root property to get two separate equations. Then, solve each equation to find the values of x.

Who needs solving quadratics by completing:

1. Students studying algebra or mathematics who are learning about quadratic equations and their solutions may need to solve quadratics by completing the square.
2. Individuals working in fields that require problem-solving skills, such as physics or engineering, may encounter quadratic equations and need to use the completing the square method.
3. Anyone interested in understanding and solving quadratic equations can benefit from knowing how to solve quadratics by completing.

It is important to note that while completing the square is one method to solve quadratic equations, there are also other techniques available, such as factoring and using the quadratic formula. The choice of method depends on the specific equation and the problem at hand.
