Ответ:
x1 = -sqrt(1154)*(im(y)^2 + re(y)^2)^(1/4)*cos(atan2(im(y, re(y))/2)/1154 - i*sqrt(1154)*(im(y)^2 + re(y)^2)^(1/4)*sin(atan2(im(y), re(y))/2)/1154)
x2 = sqrt(1154)*(im(y)^2 + re(y)^2)^(1/4)*cos(atan2(im(y, re(y))/2)/1154 + i*sqrt(1154)*(im(y)^2 + re(y)^2)^(1/4)*sin(atan2(im(y), re(y))/2)/1154)
