Question

p(x)=2x3+x2-2x+1,g(x)=x+1​

Answer 1

Answer:

2

Step-by-step explanation:

you can find other two roots by synthetic divison method

Answer 2

Answer:

As g(x) = x+1

     x+1 = 0

     x = -1

Now, p(x) = 2x3+x2-2x+1

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

         p(-1) = -2 + 2 + 2 + 1

                 = 0 + 2 + 1

                 = 3
