Question

If p(x) = 2x ^3- x^2 +3x+1 find the value of : p(-1) +p(1)/2

Answer 1

Answer:

Step-by-step explanation:

p(-1)=

2(-1)^3 - (-1)^2 +3(-1) + 1 = 2(-1) - (1) -3 +1

= -2 -1-3 + 1 = -5 ans

when p(1) = 2(1)^3 _ (1)^2 + 3 (1) +1

= 2(1) - 1 +3 +1 = 2-1+3+1

=6 -1  =5 ans (bodmas rule)

p(-1) + p(1) / 2

= (-5 + 5 )/2

=(0)/2
