Consider the following sols = Solve[x^3 + 2*x^2 - 1 == 0] {{x -> -1}, {x -> (1/2)*(-1 - Sqrt[5])}, {x -> (1/2)*(-1 + Sqrt[5])}} Why do they appear the warning messages in the following command? x^3 + 2*x^2 - 1 == 0 /. sols N::meprec: Internal precision limit $MaxExtraPrecision = 49.99999999999999` \ reached while evaluating \!\(\(-1\) + 1\/2\ \((\(-1\) - \@5)\)\^2 + 1\/8\ \(\(\((\(-1\) - \ \@5)\)\^3\)\(.\)\)\) N::meprec: Internal precision limit $MaxExtraPrecision = 49.99999999999999` \ reached while evaluating \!\(\(-1\) + 1\/2\ \((\(-1\) - \@5)\)\^2 + 1\/8\ \(\(\((\(-1\) - \ \@5)\)\^3\)\(.\)\)\) {True, -1 + (1/2)*(-1 - Sqrt[5])^2 + (1/8)*(-1 - Sqrt[5])^3 == 0, -1 + (1/2)*(-1 + Sqrt[5])^2 + (1/8)*(-1 + Sqrt[5])^3 == 0} which they don't avoid the verification FullSimplify[%] {True,True,True} Is it a way to avoid the messages (apart from turn off the message)? The following seems not to help. Block[{$MaxExtraPrecision = 1000}, x^3 + 2*x^2 - 1 == 0 /. sols] Thanks a lot
