Question

Given p(x), find p(-1) by using synthetic substitution.

p(x)=7x^3-6x^2+39x-104

p(-1)= _______

Answer 1

Answer:

  p (-1)  = -156

Step-by-step explanation:

Explanation:-

Given polynomial

           p(x)=7x³ -6x²+39x-104

Put x=-1

          p (-1)    = 7 ( -1 )³ - 6 ( -1 )² + 39 (-1 ) - 104

                     = - 7 - 6 - 39 - 104

          p (-1)  = -156
