Answer:

2

Explanations:

The given expression is:


y^2\text{ - 5y - 4}

To get the value of the expression when y = 6, we are going to substitute y for 6 in the given expression:


6^2-\text{ 5(6) - 4}
\begin{gathered} \text{Note:} \\ 6^2\text{ = 6 }*6=36 \\ 5(6)\text{ = 5 }*6=\text{ 30} \end{gathered}

The value of the expression then becomes:

36 - 30 - 4

= 6 - 4

= 2
