Remember i=sqrt%28-1%29

+sqrt%28-50%29+-+sqrt%28-8%29=sqrt%2825%29%2Asqrt%28-1%29%2Asqrt%282%29-sqrt%284%29%2Asqrt%28-1%29%2Asqrt%282%29=5i%2Asqrt%282%29-2i%2Asqrt%282%29=%285i-2i%29%2Asqrt%282%29=3i%2Asqrt%282%29


So +sqrt%28-50%29+-+sqrt%28-8%29=3i%2Asqrt%282%29 which is now in a%2Bbi form where a=0 and b=3%2Asqrt%282%29
