If the tangent line to y = f (x) at x = a is the same as the tangent line to y = g(x) at x = b, find two equations that must be satisfied by a and b.(adsbygoogle = window.adsbygoogle || []).push({});

I don't understand how to go about this problem. I tried putting the equations of the tangent lines together using the variables in the problem but i don't know what to do with my results. This is all the info i have. Any help is appreciated.
