Given the following quadratic equations. Name the form and list all the information you can get from each form.

This is in factored form. You can immediately see that the roots of the quadratic (the values of x for which y=0) are 4 and -2.This is in standard form. You can see that the y-intercept (the value of y when x=0) is -8.This is in vertex form. This tells you that the vertex of the quadratic is (1,-9).

Add up all the sides
