Solution

The given expression is,
$2 p^{2} + 5 q - 3$
We need to find the value of the given expression at $p = - 1, q = 1 / 5$
we have,
$2 p^{2} + 5 q - 3$ at $p = - 1, q = 1 / 5$
$\Rightarrow 2 {(- 1)}^{2} + 5 (1 / 5) - 3 \Rightarrow 2 (1) + 1 - 3 \Rightarrow 2 + 1 - 3 \Rightarrow 0$
Thus,
The value of the given expression $= 0$
