you can solve it by using either roots() or solve()
However if you use the (2) arguments version, the result domain is the one set in your program settings: Tools > Options > Calculation > Roots (range)
This is by default set between -20 and 20, hence the error (no roots in that domain); also, because each user might have different settings, these (2) arguments functions are probably better used as on-the-fly tools.
If you want environment-indipendant results I suggest you to use the (4) arguments alternative, where limits are explicit.
