Non linear simultaneous equations

An interactive geogebra applet that aids modeling of solving linear/non-linear simultaneous equations. Use the sliders to select the example type from…

linear/quadratic
linear/circle
quadratic/quadratic
circle/quadratic

…and generate an example using the black button. All examples have rational roots so the quadratic formula will not be needed. Click the substitute button to reveal the first line of modeling/working and then click each line of working to reveal the next. The graphs are also shown to reinforce the graphical link of the algebraic process.

The geogebra applet is attached but if you don’t have it installed then the web link is also attached so you can use the applet in a web browser.

I have attached two versions. One where the circle are limited to (0,0) centers as in GCSE study and one where it is not as in A-level study.
