SOLVE

Suggestion: CAS is optimized for exact and symbolic math, not for approximate math, which is what Home is optimized for. Introducing decimal points anywhere in your command line tells CAS to assume that the inputs are approximate, not exact. Therefore, replace the floating-point values in your expression with exact values, such as replacing "/0.4" with "*5/2", and "*0.03" with "*3/100". When I do this for your expression, CAS yields these two solutions: −0.318312076607 and 0.995115519271
