-Standard form is written y=ax^2+bx+c
-Standard form is most helpful to find the y intercept by making x zero -To change standard form to vertex form you have to complete the squares. To do this take the middle term b devide by 2 and multiply the number by its self (b/2)^2 then add and sub that value in the appropriate places adn change to vertex form. |
-The quadratic formula is shown on the image to the right
-This formula is commonly used to find the zeros of a parabola -All you have to do is make sure the equation is in standard form and plug in the corresponding letter with the corresponding numbers -Then you change the squared number to positive and negative to get your two roots |
