if x = -1 , p(x)x²+2x+1​

Answer 1

Answer:

Step-by-step explanation:1-2+1=0

(x+1)^2

Answer 2

Step-by-step explanation:

p

$p(x)x ^{2} + 2x + 1 \\ putting \: the \: value \: of \: x \: in \: the \: above \: equation \\ \\ p( - 1) -1 ^{2} + 2( - 1) + 1 \\ 1p - 2 + 1 \\ 1p = 2 - 1 \\ 1p = 3 \\ p = 3$
