Quadratic Function: Factor Form
Factor form
Below is the graph of a Quadratic function in Factor Form.
You can move the sliders to make changes to the graph.
f(x)=(x+a)(x+b)
1
When a=1 and b=1, what are the roots?
2
When a=2 and b=2, what are the roots?
3
When a=-2 and b=3, what are the roots?
4
Compare the factors to the roots, what do you notice? (Play around with the applet until you notice.
