Question

determine whether -2 is zero if polynomial is X3-3x+2=0​

Answer 1

Answer:

p(x) = x3 + 4x2 - 3x - 18  

Now, 2 will be a zero of the polynomial if p(2) = 0.  

We have:  

p(2) = (2)3 + 4(2)2 - 3(2) - 18  

      = 8 + 16 - 6 - 18  

      = 24 - 24  

      = 0

Thus, 2 is a zero of the polynomial x3 + 4x2 - 3x - 18.
