# Rational parametrization of affine curve [closed]

Why is there error evaluating this?

```
B.<x,y> = AffineSpace(QQ,2)
p=Curve([3*x^2 + 2*y^2 - 5],B)
p.rational_parameterization()
```

Works fine for me in sage 10.2.beta5. Are you using an old sage version ?

Yes I use SageMath 8.9 because I do not feel like to install Linux that is need for current version. By the way what is the last version that can be installed on Windows without the need of Linux... and is it still available for download?

Please check this guide for installing Sage in Windows: https://doc.sagemath.org/html/en/inst...

That is what I am talking about...First step - "Enable Windows Subsystem for Linux (WSL)" - in previous versions I did not need any Linux.

This is how it works now.
