Question

(x+1) is a factor of x3 -x 2 -(2+√2)x+√2 or not.​

Answer 1

Answer:

Applying remainder theorem, we get

x+1=0

x=−1

Now,

x3−x2−(2+2)x+2

Replacing x with −1, we get

=(−1)3−(−1)2−(2+2)(−1)+2

=−1−1+2+2+2

=22

Hence, (x+1) is not a factor of polynomial x3−x2−(2+2)x+2

Answer 2

x+1=0

x=-1

Step-by-step explanation:

we get x -1 now put -1 in place of x

-1 ×3 -1 -2 -(2+√2) (-1) +√2

-3 +2 + (2+√2) ×1 +√2

-3 +2 +2 +√2 +√2

1 + 2√2
