Suppose $f(x)$ has the following properties:

$f(5)=8$

$f(8)=7$

${\displaystyle \underset{5}{\overset{8}{}}}f(x)dx=14$

${\displaystyle \underset{5}{\overset{8}{}}}xf(x)dx=17$

${\displaystyle \underset{5}{\overset{8}{}}}{x}^{2}f(x)dx=17$

Evaluate:

${\displaystyle \underset{5}{\overset{8}{}}}(9x^2-4x1)f^{\text{'}}(x)dx=$
