Question

Use synthetic division and the Remainder Theorem to evaluate P(c):  P(x)=x^3-x^2+x+5; c=1

Answer 1

1⌋      1         -1        1          5

                       1        0          1 

          1           0       1          6

 

P(1) = remainder when P(x) is divided by x - 1

         = 6
