(ii) If p = -10, find the value of p2

-2p – 100.​

Answer 1

Answer:

1. 10× 20-3(10-10)

= 200-3(0)

= 200-3

=197.

hope it helps you

Answer 2

Step-by-step explanation:

$z = 10 \: then \: z^{2} - 3(z - 10) \\ = 100 - 3(0) \\ = 100 - 0 \\ = 100$

$p = - 10 \: then \: p2 - 2p - 100 \\ 100 - ( - 20) - 100 \\ 100 + 20 - 100 \\ 20$
