Question

use the factor theorem to determine g(x) is a factor of P(x) in the following case p(x)=2x³+x²-2x+1 and g(x)=x +1​

Answer 1

Step-by-step explanation:

g(x)= 0

x+1=0

x= —1

put the x= —1 in p(x)

p(—1)= 2×(—1)³+ (-1)²— 2×—1+1

p(—1)= —2+1+2+1

p(—1)= 2

so, x—1 is not a factor of p(x).
