With the application of some algebra, this will become a quadratic.
You can then use the well-known "quadratic formula" to solve for r.

A search is not necessary. It can be solved analytically.

If this is homework, do it yourself. If you are unable to do simple
algebra or find a common formula on the web, and program for
a living, you have chosen the wrong career.
I suggest more care in choosing subject lines in the future. I and
some other people find it difficult to bother looking at a post when
the author cannot bother to do such a simple thing in order to save
readers' time.
