Question

Find the reminder when P(x) = x²+2×+1 is divided by (x+2).​

Answer 1

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

Plz follow me

Answer 2

Remainder = 1.
