\(=-\dfrac{19}{4}\cdot\dfrac{14}{3}-\dfrac{25}{3}\cdot\dfrac{19}{4}+\dfrac{19}{4}=\dfrac{19}{4}\left(-\dfrac{14}{3}-\dfrac{25}{3}+1\right)=\dfrac{19}{4}\cdot\left(-12\right)=-57\)
\(-\dfrac{19}{3}\cdot\dfrac{14}{4}-\dfrac{25}{3}\cdot\dfrac{19}{4}+4\dfrac{3}{4}\)
\(=-\dfrac{19}{4}\left(\dfrac{14}{3}+\dfrac{25}{3}\right)+\dfrac{19}{4}\) \(=-\dfrac{19}{4}\cdot13+\dfrac{19}{4}=-\dfrac{228}{4}=-57\)
= \(\dfrac{-19}{3} . \dfrac{14}{4} + \dfrac{-25}{3} . \dfrac{19}{4} + \dfrac{19}{4} \)
= \(\dfrac{19}{4}(\dfrac{-14}{3} + \dfrac{-25}{3} + 1\))
= \(\dfrac{19}{4} . (-12)\)
= - 57
