Question

use the factor theorem to determine whether g(x) is factor of p(x) in each of the following cases.

1. p(x) =2x³+x²-2x-¹
g(x) =x+1.
2.p(x)=4x²+x+6
g(x)=x-3​

Answer 1

Step-by-step explanation:

1 ) Apply factor theorem 

x+1=0

So x=−1

2x3+x2−2x−1

Replace x by −1, we get

2(−1)3+(−1)2−2(−1)−1=−2+1+2−1=0

Reminder is 0 so that x+1 is a factor of 2x3+x2−2x−1
