 Find an approximating polynom of known degree for a given data.
 ===Example===
 For input data:
- x = {0,  1,  2,  3,  4,  5,  6,  7,  8,  9, 10};
+ x = {0,  1,  2,  3,  4,  5,  6,   7,   8,   9,   10};
- y = {1,   6,  17,  34,  57,  86, 121, 162, 209, 262, 321};
+ y = {1,  6,  17, 34, 57, 86, 121, 162, 209, 262, 321};
-The approximatting polynom is:
+The approximating polynom is:
+x<sup>2</sup> + 2 x + 1
+Here, the polynom's coefficients are (3, 2, 1).
-x + 2 x + 1
-Here, polynom's coefficients are (3, 2, 1).
