- Find R1 and R2

- Relevant Equations
- (R1+R2 +Ro) /R2 = 5 where Ro = SQRT(R1 x R2+(R1 x R1) / 4) = 60

Greetings, fellow travelers.

I gave been digging into some of my old (1970s) Electronic maths textbooks and for my amusement and time wasting refreshing some old knowledge. Have got through a fair but but have to keep coming back to this problem.

I do have the answers but I cannot regardless of how I manipulate the variables I can't seem to find the correct method obtain the answer. This problem is in part of the book related to solving quadratics but I can't see how this is related. Any broad hints at a solution would help me sleep better. Thanks for your assistance.

PS sorry about the format of the equations. Havent used the system to enter equations before. Maybe I will learn that too!
