Evaluate the expression for n = –1.9 and p = 8.

To evaluate the expression \( n^2p - p \) for \( n = -1.9 \) and \( p = 8 \), we start by calculating \( n^2 \).

1. Calculate \( n^2 \): \[ n^2 = (-1.9)^2 = 3.61 \]

2. Now, substitute \( n^2 \) and \( p \) into the expression: \[ n^2p - p = 3.61 \times 8 - 8 \]

3. Calculate \( 3.61 \times 8 \): \[ 3.61 \times 8 = 28.88 \]

4. Now, complete the expression: \[ 28.88 - 8 = 20.88 \]

Thus, the evaluated expression is: \[ \boxed{20.88} \]
