%28-9-+sqrt%28-2%29%29%5E2

%28-9-+i%2Asqrt%282%29%29%5E2

%28-9%29%5E2+%2B+2%28-9%29%28-i%2Asqrt%282%29%29+%2B+%28-i%2Asqrt%282%29%29%5E2

81+%2B+18i%2Asqrt%282%29+%2B+2i%5E2

81+%2B+18i%2Asqrt%282%29+%2B+2%28-1%29

79+%2B+18%2Asqrt%282%29%2Ai
=======================================================

So,

%28-9-+sqrt%28-2%29%29%5E2+=+79+%2B+18%2Asqrt%282%29%2Ai
