If you typed exactly what you posted, then the problem is you are not using correct syntax. Specifially, Mathematica is case sensitive and typing something in all caps will do exactly as you describe. Try

Solve[x^4 - 1 == 3, x]

Note the case of Solve, usage of "[" instead of "(" and "==" instead of "=". Also, this will give you all 4 solutions not just the two real solutions.
