In this section, you will use square roots to learn another way to solve quadratic equations—and this method will work with all quadratic equations. In a previous video concerning quadratics we did not include the integer preceding the quadratic expression in the equation to solve for the zero's of the function. Algebra II on Khan Academy: Your studies in algebra 1 have built a solid foundation from which you can explore linear equations, inequalities, and functions. Solve the equation. Adding 49 on both sides. Solve Quadratic Equations of the Form a (x h) 2 = k Using the Square Root Property We can use the Square Root Property to solve an equation like (x 3) 2 = 16, too. Example 1: Solve the following equations for and enter exact answers only (no decimal approximations). Isolate all x^2 terms on one side and take the √ of both sides to calculate x. Divide by 3 on both sides. Free trial available at KutaSoftware. Dividing by 2 on both sides. This is because when we square a solution, the result is always positive. com Solve simple quadratic equations by taking the square root of both sides of the equation. com Create your own worksheets like this one with Infinite Algebra 1. Analyze the process of solving a quadratic equation by taking the square root. If there is more than one solution, separate your answers with commas. Demonstrates how to solve quadratics by the process of taking the square root of both sides. Create your own worksheets like this one with Infinite Algebra 1. Subtracting 2 on both sides. Solving Quadratic Equations by Taking Square Roots Problems Solve each of the following quadratic equations by taking square roots. Quadratic equations differ from linear equations by including a quadratic term with the variable raised to the second power of the form a x 2. We use . Demonstrates how to solve quadratics by the process of taking the square root of both sides. Enter the solutions from least to greatest. Solve a Quadratic Equation by the Square Root Property One way to solve the quadratic equation x 2 = 9 is to subtract 9 from both sides to get one side equal to 0: x 2 When solving quadratic equations by taking square roots, both the positive and negative square roots are solutions to the equation.
