Is there a closed form?

Can anyone help me to find the coefficient of \(x^{49}\) in \[ \displaystyle \prod_{r=1}^{50} [x - r(51-r)]? \]

Coefficient of \(x^{49}\) is equivalent to finding the sum of the roots of the equation if the expression is equated to zero.

In this case , \(\displaystyle [x^{49}] = \sum_{r=1}^{50}r(51-r) = 22100\)
