Question

Can someone answer this pls??

Answer 1

Step-by-step explanation

• 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

`(2( - 1) + 1(1) + 1)/( - 1) \\ ( - 2 + 1 + 1)/( - 1) \\ ( - 2 + 2)/( - 1) \\ (0)/( - 1) \Longrightarrow 0`

Answer

`\large \boxed{0}`
