One of the ways we can solve a quadratic equation is by factoring This means we rearrange the quadratic equation into the factored form 0 From here it is possible to deduce that both and satisfy the equation and that they are therefore solutions of the equation In this chapter we have been solving quadratic equations of the form ax2 bx c 0 We solved for xx and the results were the solutions to the equation We are now looking at quadratic equations in two variables of the form y ax2 bx c The graphs of these equations are parabolas
Identify the number of solutions of a quadratic equation Solve quadratic equations by graphing Analyze quadratic functions using a graphing calculator Solve real world problems by graphing quadratic functions We can plot the graph of a quadratic function by drawing a table of values for the xx and yy coordinates and then plotting these on a set of axes Once we have drawn the graph of the quadratic function we can use the graph to find key points For a quadratic these are
