Question

determine x+1 is a factor of x³-2x²-(2+√2)x-√2 or not​

Answer 1

Answer:

iv)x³−x²−(2+2)x+2=(−1)3−(−1)2−(2+2)(−1)+2=−1−1+2−2+2=0

This is zero. Then x+1 is the factor of equation

Answer 2

Answer:

we know that x+1=0

so,x=-1

By substituting the value in the equation

(-1)^3 - 2(-1)^2 - (2+√2)-1 - √2

(-1) -(2) +2 -(√2) -√2

=0
