In my book it says that the equation

*ax²=b*can be written in the form

*x²=a/b*but I don't understand how they've done that.

If I were to rearrange it, I always get

*x²=*because I think since the

**b**/a*b*is already on the right, the

*a*must go underneath.

Is there some rule that lets you rearrange as my book says or is it wrong?

Thank you very much.
