Solve the following quadratic equations by extracting square roots. Solve x 2 – 4 = 0; On the previous page, I'd solved this quadratic equation by factoring the difference of squares on the left-hand side of the equation, and then setting each factor equal to zero, etc, etc. Key Strategy in Solving Quadratic Equations using the Square Root Method. There are other ways of working out square roots on this page. The idea is to take any quadratic equation in standard form and complete the square so that we can solve it by extracting roots. Roots are the inverse of exponents, much like multiplication is the inverse of division. The latest ones have updated on 11th December 2020. The side of the equation containing the variable (the left side) is a perfect square, so we'll take the square root of both sides to solve the equation. Solution: The -4 tells us that, from the parent graph, the function will shift to the right four units. Here's one we'll use: 46656 First, divide the number to be square-rooted into pairs of digits, starting at the decimal point.
