# Thread: 1 unknown equation solver

1. ## 1 unknown equation solver

I've revamped our original equation solver to include inequalities and multiple variable terms and constants.

Limitations are no powers are allowed, and only one variable [a-z] is allowed. This comes complete with a quiz generator, shortcut commands, and a practice problem generator. If what you enter is an inequality, the calculator will link to the interval notation representation at the end of the calculation.

The following are examples of what the calculator can handle including the shortcut commands:

$\displaystyle 2x=6$

$\displaystyle 9x - 12<=20$

$\displaystyle -x + 2 + 10x - 9 -6 >= -3 + 4x + 40 - 8x$

2. This lesson now handles expressions with parentheses in them, including shortcuts entered directly on the search engine.

3. The calculator now solves square root equations in the form ax^2 = c or ax^2 + b = c. Shortcuts are accepted now as well in the search engine.

By early next week, this will handle cube root and other positive roots in the form mentioned above as well.

4. I've added square root equations of the form asqrt(bx)=c where x is any variable a-z. You can shortcut these as well.
