Question

find the remainder when 4y^3-3y^2+2y-1 divided by y+2.
option :a.23
b.25
c.-39
d.-49​

Answer 1

oolow 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
