This algebra solver allows you to solve for any parameter of linear, parabolic, and dual linear equations. In both numeric and graphical presentations there are convenient sliders to set values of the independent or dependent parameters to help with linear and quadratic formulas.

The app has 4 main panels - linear (y = mx+b); quadratic polynomial (y = ax^2 + bx + c); quadratic factored (y = (x+a)(x+b); and dual linear (ay=bx+c, dy=ex+ f). In the front panel there are text entries and sliders for each parameter and a lock button to choose the dependent variable (e.g. the one that is solved). On the flipside of each is a graph of the equation with an additional slider and text box to change any of the values while solving for y or x.

The dual linear solves for the intersection of the two lines.

This is a quick way to visualize algebra problems, prepare for tests, check homework, or solve precision problems.
