If these are the solutions, I can say
+x+=+-3.3+ and
+x+=+.3+
-----------
It is also true
+x+%2B+3.3+=+0+
+x+-+.3+=+0+
-----------
Now multiply left sides and
set equal to zero
+%28+x+%2B+3.3+%29%2A%28+x+-+.3+%29+=+0+
+x%5E2+%2B+3.3x+-+.3x+-+.99+=+0+
+x%5E2+%2B+3x+-+.99+=+0+
The quadratic equation is
+f%28x%29+=+x%5E2+%2B+3x+-+.99+
