Answer 1

Answer:

it is your answer

Answer: P(2)=2+(2)+2(2)^{2}-(2)^{3} P(2)=4+8-8 P(2)=4

Answer 2

$\large\green{\textsf{✩ Verified Answer ✓ }}$

p(x) = 3x³ - 2x² - x + 4

p(- 1) = 3(-1)³ - 2(-1)² - (-1) + 4

p(- 1) = 3 × (-1) - 2 × 1 + 1 + 4

p(- 1) = - 3 - 2 + 5

p(- 1) = - 5 + 5 = 0

p(- 1) = 0

So, as per Factor Theorem

-1 is zero if p(x)

hope it helps you :)
