You would type sqrt( -44 ) to mean sqrt%28-44%29 (sqrt is shorthand for square root)


sqrt%28-44%29+=+sqrt%28-1%2A4%2A11%29 Factor -44 by factoring out -1 and factor 44 where one factor is a perfect square


sqrt%28-44%29+=+sqrt%28-1%29%2Asqrt%284%29%2Asqrt%2811%29 Break up the root using the rule sqrt%28x%2Ay%29+=+sqrt%28x%29%2Asqrt%28y%29


sqrt%28-44%29+=+i%2A2%2Asqrt%2811%29 Note: i+=+sqrt%28-1%29 by definition


sqrt%28-44%29+=+2i%2Asqrt%2811%29
