Question

x3- x2 - (2 + V2)x+ 12
pla give right awnser​

Answer 1

Answer:

Apply remainder theorem

x+1=0

x=−1

Put the value of x=−1 in all equations.

This is not zero.Then x+1 is not the factor of equation

(iii) x⁴+3x³ +3x ²+x+1=(−1)⁴+3(−1)³+3(−1)²+(−1)+1=1

This is not zero.Then x+1 is not the factor of equation

(iv)x 3 −x 2−(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
