Answer 2

Answer:

i)0

ii)-1

Other question's ii)k = -√2/2

I solved literally all of these in my mind itself so last one might be wrong

Explanation:

i)

x + 1 = 0

x = - 1

p(-1) = 2(-1)^3 + (-1)^2 -2×(-1) - 1

-2 +1 + 2 - 1

= 0

ii)x +2 = 0

x = -2

p(-2) = (-2)^3 + 3(-2)^2 + 3×(-2) + 1

-8 + 12 -6 + 1

4 - 5

= -1

ii) other part

x - 1 = 0

x = 1

p(1) = 2(1)^2 + k×1 + √2 = 0

2 + k + √2 = 0

I got confused between these 2 options

I)k = -√2 -2

ii)2k = -√2

k = -√2/2

hope that helps you
