Real examples and applications are messy, with ugly roots made of decimals or irrational numbers. Here's Dr. Loh's explainer video: Quadratic equations fall into an interesting donut hole in education. Quadratic equations are polynomials that include an x², and teachers use them to teach students to find two solutions at once. Dr. Loh's method, which he also shared in detail on his website, uses the idea of the two roots of every quadratic equation to make a simpler way to derive those roots. Dr. Loh's new method is for real life, but he hopes it will also help students feel they understand the quadratic formula better at the same time. The new process, developed by Dr. Po-Shen Loh at Carnegie Mellon University, goes around traditional methods like completing the square and turns finding roots into a simpler thing involving fewer steps that are also more intuitive. If students can remember some simple generalizations about roots, they can decide where to go next. Remember that taking the square root of both sides will give you a positive and negative number.

Let's solve them together. This simplifies the arithmetic part of multiplying the formula out. Pull terms out from under the radical, assuming positive real numbers. Next, use the negative value of the to find the second solution. The same thing happens with the Pythagorean theorem, where in school, most examples end up solving out to Pythagorean triples, the small set of integer values that work cleanly into the Pythagorean theorem. A mathematician at Carnegie Mellon University has developed an easier way to solve quadratic equations. If you have x², that means two root values, in a shape like a circle or arc that makes two crossings. Try Numerade free for 7 days. U2.6 solve quadratic by completing the square. Understanding them is key to the beginning ideas of precalculus, for example.
Dr. Loh believes students can learn this method more intuitively, partly because there's not a special, separate formula required. If the two numbers we're looking for, added together, equal 8, then they must be equidistant from their average. An expression like "x + 4" is a polynomial. The complete solution is the result of both the positive and negative portions of the solution. Answered step-by-step.
