    The result is: $x \left(x - 5\right) \left(x - 4\right) \left(x - 3\right) \left(x - 2\right) + x \left(x - 5\right) \left(x - 4\right) \left(x - 3\right) \left(x - 1\right) + x \left(x - 5\right) \left(x - 4\right) \left(x - 2\right) \left(x - 1\right) + x \left(x - 5\right) \left(x - 3\right) \left(x - 2\right) \left(x - 1\right) + x \left(x - 4\right) \left(x - 3\right) \left(x - 2\right) \left(x - 1\right) + \left(x - 5\right) \left(x - 4\right) \left(x - 3\right) \left(x - 2\right) \left(x - 1\right)$
  So, the result is: $- \frac{x \left(x - 5\right) \left(x - 4\right) \left(x - 3\right) \left(x - 2\right)}{720} - \frac{x \left(x - 5\right) \left(x - 4\right) \left(x - 3\right) \left(x - 1\right)}{720} - \frac{x \left(x - 5\right) \left(x - 4\right) \left(x - 2\right) \left(x - 1\right)}{720} - \frac{x \left(x - 5\right) \left(x - 3\right) \left(x - 2\right) \left(x - 1\right)}{720} - \frac{x \left(x - 4\right) \left(x - 3\right) \left(x - 2\right) \left(x - 1\right)}{720} - \frac{\left(x - 5\right) \left(x - 4\right) \left(x - 3\right) \left(x - 2\right) \left(x - 1\right)}{720}$
The result is: $\frac{a \left(2 x - 1\right)}{2} - \frac{x \left(x - 5\right) \left(x - 4\right) \left(x - 3\right) \left(x - 2\right)}{720} - \frac{x \left(x - 5\right) \left(x - 4\right) \left(x - 3\right) \left(x - 1\right)}{720} - \frac{x \left(x - 5\right) \left(x - 4\right) \left(x - 2\right) \left(x - 1\right)}{720} - \frac{x \left(x - 5\right) \left(x - 3\right) \left(x - 2\right) \left(x - 1\right)}{720} - \frac{x \left(x - 4\right) \left(x - 3\right) \left(x - 2\right) \left(x - 1\right)}{720} - \frac{x \left(x - 4\right) \left(x - 3\right) \left(x - 2\right)}{120} - \frac{x \left(x - 4\right) \left(x - 3\right) \left(x - 1\right)}{120} - \frac{x \left(x - 4\right) \left(x - 2\right) \left(x - 1\right)}{120} - \frac{x \left(x - 3\right) \left(x - 2\right) \left(x - 1\right)}{120} - \frac{x \left(x - 3\right) \left(x - 2\right)}{24} - \frac{x \left(x - 3\right) \left(x - 1\right)}{24} - \frac{x \left(x - 2\right) \left(x - 1\right)}{24} - \frac{x \left(x - 2\right)}{6} - \frac{x \left(x - 1\right)}{6} - \frac{\left(x - 5\right) \left(x - 4\right) \left(x - 3\right) \left(x - 2\right) \left(x - 1\right)}{720} - \frac{\left(x - 4\right) \left(x - 3\right) \left(x - 2\right) \left(x - 1\right)}{120} - \frac{\left(x - 3\right) \left(x - 2\right) \left(x - 1\right)}{24} - \frac{\left(x - 2\right) \left(x - 1\right)}{6}$
Now simplify:

$a x - \frac{a}{2} - \frac{x^{5}}{120} + \frac{x^{4}}{16} - \frac{11 x^{3}}{36} + \frac{5 x^{2}}{16} + \frac{7 x}{45} - \frac{7}{60}$

The answer is:

$a x - \frac{a}{2} - \frac{x^{5}}{120} + \frac{x^{4}}{16} - \frac{11 x^{3}}{36} + \frac{5 x^{2}}{16} + \frac{7 x}{45} - \frac{7}{60}$
