Use synthetic division and the Remainder Theorem to find P(a).

Question

 

a. 50
b. 950
c. –4
d. –438

Answer 1

Start with Synthetic Division:

 

-4 |    1    -9     5      -7      10

                 -4    52  -228   940

--------------------------------------------

          1    -13    57   -235    950

 

The remainder theorem tells us that the remainder we just got (950) is equal to P(-4).
