How it works ?
Copy each problem this applet generates on a separate sheet of paper.
Simplify this expression.
After simplifying, enter in the coefficients you obtain in the appropriate input boxes.
Once both coefficients are entered correctly, the applet will indicate this to you.
Note: Ignore the “.” in front of the second input box. (Just pretend it’s not there.)
Work through as many times as you need in order to master this concept!
