Standard form of a quadratic equation: Yesterday when we graphed quadratic equations we used the same x values in our tables because the equations we graphed did not have any “b” values. If you were to graph y = x2 + 6x + 8 and used the same x values as we did yesterday, what kind of shape would the graph make? y = x2 + 6x + 8

You have seen that a quadratic equation of the form (x-p)(x-q)= 0 has roots p and q. You can use this pattern to find a quadratic equation for a given pair of roots. Chapter 6: Quadratic Functions and Inequalities Section 4: Completing the Square. Square Root Property Examples For equations like x2 – 25 = 0, you can solve by factoring.
