Question

find the value of p(1)+p(-1) for the polynomial p(×)=×3- 2×2-5×+3​

Answer 1

Answer:

p ( 1 ) = 1^3 - 2*1^2 - 5*1 + 3

= 1 - 2 - 5 + 3

= 1 - 2 - 2

= 1 - 4

= - 3

p ( -1 ) = -1^3 - 2*(-1)^2 - 5*(-1) + 3

= -1 - 2 + 5 + 3

= -1 - 2 + 8

= -3 + 8

= 5

= p(1) + p(-1)

= -3 + 5

= 2

hope it helps
