If something is the complementary angle to itself, it must be 45, because only 45*2 is 90.
45=x%5E2-x%2B50
Subtract 45 from both sides
0=x%5E2-x%2B5
Use the quadratic formula:
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%281+%2B-+sqrt%28+1%5E2-4%2A1%2A5+%29%29%2F%282%2A1%29+
x+=+%281+%2B-+sqrt%28+1-20+%29%29%2F%282%29+
x+=+%281+%2B-+sqrt%28+-19+%29%29%2F%282%29+
There is no real sqrt of -19.
