Question

1.  If x²+2x-1 is divided by x+1, the remainder is 



2. The value of √n, where n is an even positive integer, is ​

Answer 1

$\huge\mathfrak\pink{Answer}$

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

I hope it will help you army ☺️✌️
