ln x + ln(x-2) = 1
ln [x(x-2)] = 1
x(x-2) = e
x%5E2+-+2x+-+e+=+0

+x+=+%28-b+%2B-+sqrt%28b%5E2+-+4ac%29%29%2F%282a%29
+x+=+%282+%2B-+sqrt%28%28-2%29%5E2+-+4%281%29%28-e%29%29%29%2F%282%281%29%29
+x+=+%282+%2B-+sqrt%284+%2B+4e%29%29%2F2
+x+=+%282+%2B-+sqrt%284%281+%2B+e%29%29%29%2F2
+x+=+%282+%2B-+sqrt%284%29%2Asqrt%281+%2B+e%29%29%2F2
+x+=+%282+%2B-+2sqrt%281+%2B+e%29%29%2F2
+x+=+2%281+%2B-+sqrt%281+%2B+e%29%29%2F2
+x+=+1+%2B-+sqrt%281+%2B+e%29
