Question

divide the polynomial 2x4+5x3-2x2+2x-4 by 2x+1 and verify remainder by using remainder theorem​

Answer 1

Answer:

2x4 + 5x3 - 2x2 + 2x + 1 = -1

Step-by-step explanation:

2x4 + 5x3 - 2x2 + 2x + 1 is divided by 2x + 1 then

x = -1 / 2 is put in the equation

2 ( -1/2)4 + 5(-1/2)3 - 2(-1/2)2 + 2(-1/2) + 1

1/8 - 5/8 - 1/2 - 1 + 1

take lcm

(1- 5- 4)/8

-8/8

-1

sorry if the answer is wrong
