Solving Quadratics by the Square Root Principle
Solving Quadratics by the Square root Principle Pike Page 1 of 3 Solving Quadratics by the Square root Principle The Square root Principle is a technique that can be used to solve Quadratics , but in order to solve a quadratic using the Square root Principle the problem must be in the correct form. To solve a quadratic using the Square root Principle the quadratic must be in vertex form, a(x h)2 + k. In other words, the quadratic must have a perfect Square such as (x + 5)2 and no other x s in the problem. Consider the following two examples: 2(x 4)2 + 7 = 19, this problem can be solved using the Square root Principle because there is a perfect Square , (x 4)2, and there is only one x in the problem. 2(x 4)2 + 7x = 19, this problem cannot be solved using the Square root Principle because even though there is a perfect Square , (x 4)2, there is a second x in the problem.
