Question

1. Find the remainder when 2x®+ x + 2x - 1 is divided
by X+1​

Answer 1

foolow the process

for finding the remainder we need to use remainder theorom

let p(x)=x  

2

+2x+1

Here, the divisor is x+1 for dividend p(x), we need to equate it to 0 and put that value of x in p(x).

−x+1=0

∴x=−1

p(−1)=(−1)  

2

+2(−1)+1=0

Hence, remainder=0
