Question

use the factor theorem to determine whether g(x) is a factor of p(x)=2x³+x²-2x-1 g(x)=x+1.
​

Answer 1

Answer:

Step-by-step explanation:

if g(x) should be a factor of p(x) then

p(-1) should be 0

so,

p(-1)=2(-1)^3+(-1)^2-2(-1)-1

     =-2+1+2-1

     = 0

since p(-1)=0

g(x)=x+1 is a factor of p(x)
