Solution

Find the required value
From the given data $p = - 10$
The given equation is
$p^{2} - 2 p - 100$
On substituting the value of p in the above algebraic equation and simplifying we get
$p^{2} - 2 p - 100 = {(- 10)}^{2} - (2 \times (- 10)) - 100 = 100 + 20 - 100 = 20$
Hence the value of $p^{2} - 2 p - 100$ is $20$
