Question

Find the value of p²- 2p - 100 , if p = -10

Answer 1

$\large\bf{Hey\:mate\:here\:is\:ur\:ans}$

p² - 2p - 100 -----(1)

given, p = -10

put value of p in (1),

(-10)² - 2(-10) - 100

= 100 + 20 - 100

= 20

Answer 2

Answer:

=> 20

Step-by-step explanation:

Given that:-

$p^2 - 2p -100$

The value of $p = -10$,

To find:- The value of the expression.

As we have,

=> $p^2 - 2p -100$

Now plug the value of p as $-10$ in the above expression,

=> $(-10)^2-2(-10)-100$

By simplifying it further, we get

=> $100 - ( -20 ) - 100$

=> $100 + 20 - 100$

=> 20

Hence, the required solution is 20.
