  • Given the expressions and values.

\frac{2ab +  {a}^{2}  {b}^{2}  - a}{ab}  \\  \begin{cases} a  =  - 1 \\ b = 1 \end{cases}

  • Substitute the value of a and b in the expression to evaluate.

\frac{2( - 1)(1) +  {( - 1)}^{2}  {(1)}^{2}  - ( - 1)}{( - 1)(1)}

  • Evaluate

\frac{2( - 1) + 1(1) + 1}{ - 1}  \\  \frac{ - 2 + 1 + 1}{ - 1}  \\  \frac{ - 2 + 2}{ - 1}  \\  \frac{0}{ - 1}  \Longrightarrow 0
