If there is no typo, the solution is complex.
(x-1)^2=-4
=>
(x-1)=±2i
so
x=1±2i
solve(x-1)^2=-4..... i used the quadratic formula but got stock ... please help thank you

There is no REAL solution.
Since the left side is something squared it must always be positive, and cannot be the value of -4 found on the right side,
or, if you allow complex numbers
x+1 = ± √-4
x = -1 ± 2i
