This approach to solving equations is based on the fact that if the product of two quantities is zero, then at least one of the quantities must be zero. For more on factoring polynomials, see the review section P. The idea behind completing the square is to rewrite the equation in a form that allows us to apply the square root principle. The reason for choosing this value is that now the left hand side of the equation is the square of a binomial two term polynomial. That is why this procedure is called completing the square. To get "a" one need only divide the x-coefficient by 2. The method of completing the square demonstrated in the previous example only works if the leading coefficient coefficient of x 2 is 1.

Solutions for over topics within math, chemistry and physics problems across all levels of education, from elementary school to college. Equations with radicals can often be simplified by raising to the appropriate power, squaring if the radical is a square root, cubing for a cube root, etc. Stacy Blackman Consulting.
