An Intro to Solving Linear Equations: Solving some Basic Linear Equations

      Solving matrix equations


      By Khan Academy

      After he represented a system of equations with a single matrix equation, Sal solves that matrix equation using the inverse of the coefficient matrix.

          Radical equations


          By Khan Academy

          Sal explains what square-root equations are, and shows an example of solving such an equation and checking for extraneous solutions.

              Graphing Quadratic Equations


              By Marc Whitaker

              Instructor uses a white board to model graphing quadratic equations. Examples show using quadratic equations in standard form to determine the line of symmetry, create a table of values, and graph the quadratic equation by using these values.
