1. The problem statement, all variables and given/known data Determine equations of all lines the are tangent to y=x^2/(x-1) and that pass through the point (2,0). 2. Relevant equations 3. The attempt at a solution First I found the y' which I came up with y'=x(x-2)/(x-1)^2 next, let (a,f(a)) and put a to y' f'(a)=a(a-2)/(a-1)^2 (slope of tangent lines at x=a) ->① also this slope is given by f(a)-0/a-2 -> ② ①=② then solve for a, but I stuck for calculating this... Am I on the right truck ?? can anyone help me, please??
