A link to the "false position method" can be placed in the Challenge description.
The syntax is .

I found the algorithm at http://math.fullerton.edu/mathews/n2003/regulafalsi/RegulaFalsiProof.pdf

will create a link with a name. Spaces before the < and after the > are needed.

The idea of the method is that the lower and upper bounds for x define a line. Wherever this line crosses the x-axis becomes our new estimate for the root (1st iteration is like the secant method). https://en.wikipedia.org/wiki/Regula_falsi

This problem needs more test cases.
