4+-+sqrt%28-50%29

4+-+sqrt%28-1%2A25%2A2%29

4+-+sqrt%28-1%29%2Asqrt%2825%29%2Asqrt%282%29

4+-+i%2A5%2Asqrt%282%29 Note: i=sqrt%28-1%29

4+-+5i%2Asqrt%282%29

4+-+%285%2Asqrt%282%29%29%2Ai

4++%2B+%28-5%2Asqrt%282%29%29%2Ai

The number is now in standard a%2Bbi form where

a+=+4

b+=+-5%2Asqrt%282%29
