Solve example on various calculators
(X+1)*sqrt(X^2 2*X 1) =0 on HP 35S, the roots at 1, ~.41 are found. The root at ~2.41 produces a negative square root error. A similar experience on the TI30X Pro…the ~2.41 root produces a no sign change error. The CASIO 991CW finds the ~2.41 root with ease, but the guess for the root at ~.41 has to be correct to about 6 significant digits to find the root. The CASIO 9750giii has the same problem in the equation app, but finds the 1 and ~.41 roots in calculate mode using SolveN and the Solve for a range of 2 to 3 finds the ~2.41 root ( a range encompassing the full range of roots only finds the ~2.41 root). Wonder how the methodologies differ amongst the calculators.
