In future courses, you will run into quadratic equations whose solutions are not real numbers. The process of completing the square can still be used to arrive at the complex answers to such equations. Here is an example of how that process will look. Find the solutions for: x2 - 5x + 7 = 0 (found in Algebra 2)
Learn how to solve quadratic equations by completing the square with step-by-step explanations, worked examples, and interactive practice problems.
The process of completing the square is a way to solve a quadratic equation. This procedure converts an equation written in the standard form of the quadratic function ax^2+bx+c ax2 + bx + c into an expression with a variable squared, as in the following example: (X-r)^2-w (X − r)2 − w where r r and w w are parameters.
What do we do with a quadratic equation that is not factorable and cannot be solved by extracting a square root? One option is to change a quadratic equation into a perfect square trinomial by using a procedure called completing the square. The following table shows examples of perfect square trinomials in different forms.
