​

Answer 1

Step-by-step explanation:

p=-1

-1 ((-1)2+(-1)+1)+5

-1 (-2+(-1))+5

2+(-1)+5

2-1+5

1+5

6

Answer 2

Solution :-

Putting p = -1, we get

$\implies \pink{\bf{ -1 (-1 × -1 -1 + 1 ) + 5 }}$

$\implies \purple{\bf{ -1 (1) + 5 }}$

$\implies \blue{\bf{ -1 + 5 }}$

$\implies \red{\bf{ 4 }}$

Hence, answer is $\color{indigo}{\mathsf{ 4 }}$
