Calculate the positive root of the polynomial (x - 1)(x - 2)(x - 3)(x - 4)- 63.	Choose one:
A) 5+√37/2
B) 4+√37/2
C) 3+√37/2
D) 2+√37/2
E) 6+√37/2
Note that   (x - 1)(x - 2)(x - 3)(x - 4) - 63 = [(x - 2)(x - 3)][(x -1)(x - 4)] - 63   = (x2-5x + 6)(x2 - 5x + 4) - 63   = [(x2 - 5x + 5 + 1)(x2 - 5x + 5 -1)] - 63   = [(x2 - 5x + 5)2 - 1] - 63   = (x2 -5x + 5)2 - 64   = (x2 - 5x + 5 + 8)(x2 -5x + 5 - 8)   = (x2 - 5x + 13)(x2- 5x - 3):   The polynomial x2 - 5x + 13 has no real roots, while the polynomial x2 -5x - 3 has roots   x=5+-√37/2.   since 5-√37/2&lt;0,   the only positive root is 5+√37/2   correct answer 5+√37/2
