FindRoot[x^2 == 4x - 4, {x, 1}] Out[4]= {x -> 1.99902} In[15]:= FindRoot[x^2 - 4*x + 4, {x, 3}] Out[15]= {x -> 2.00098} When the root is clearly two. Is Mathematica using Newton's Method like a Ti-92? Even if so, why wont it give a more accurate answer? I've tried N[%,30] but it doesn't do anything. I'm new to Mathematica coming over from a Ti-92, so everything is frustrating right now. Thanks.
