Answer 2

Let me Make it simple for You :

••••••••••••••••••••••••••••••••••••••☆☆☆☆☆☆☆☆••

Do you know remainder theorm??

It says ," Just equate the divisor to zero and put the value in dividend you will get remainder easily"

•••••••••••••••••••••••••••••••••••••••☆☆☆☆☆☆☆☆••

Lets use the theorm :

x-2 = 0

x = 2 <------- now put the value of x as 2 in dividend

$= > 2x ^{4} - x ^{3} + 2x ^{2} + x - 1$

$= > 2.(2) ^{4} - 2 ^{3} + 2.(2) ^{2} + 2 - 1$

$= > (2 \times 16 )- 8 +( 2 \times 4) + 2 - 1$

$= > 32 - 8 + 8 + 2 - 1$

$= > 32 + 8 + 2 - 8 - 1$

$= > 42 - 9$

$= > 33 \: ans \:$

The remainder will be : 33

Hope you understand please mark brainliest:)
