## How to solve a polynomial system by PHCWeb?

- Enter your polynomial system in the textarea.
- Click "Solve" button to get solutions. If the solution is large, it will take some time and you might need to click update to check the newest result.
- Give your system a name. Click on "Save as" to save it.
- If you have a similar solution with different efficients. Click on "Solve Similar", change the coefficents and use homotopy to solve your new system.

## How to manage my polynomial systems in PHCWeb?

- Click "My Polynomial Systems" on the top.
- You have entire table of all polynomials you have solved. You can check solutions and phc report. You can also transfer solution to maple or python format.
