2009 PBLPathways Solve the equation. Solving Cubic and Quartic Equations of the Form f(x) = 0 1.Determine the possible rational solutions of f(x) = 0. 2.Graph y = f(x) to see if any of the values from Step 1 are x-intercepts. The x- intercepts are also solutions to f(x) = 0. 3.Find the factors associated with the x-intercepts from Step 2. 4.Use synthetic division to divide f (x) by the factors from Step 3 to confirm the graphical solutions and find additional factors. Continue until a quadratic factor remains. 5.Use factoring or the quadratic formula to find the solutions associated with the quadratic factor. These solutions are also solutions to f(x) = 0.
