(1) Given y = (x-4)(x+2)
What form is this equation in?__________________
Let’s graph it accordingly!
axis of symmetry:
x
y
V:
What are the solutions of the factored form?________ Where are they
represented in the graph?_________________________
Now let’s solve this problem a different way
Given y = (x-4)(x+2) Dist
Distribute it out:_______________________
What form is this equation in?
in?__________________
Let’s graph it accordingly!
axis of symmetry:
