Question

if (x - 1/x)= 5 , then ( x^6 + 3x^2 -1 ) / (x^6 -8x^3 -1 ) =?​

Answer 1

Answer:

Consider the following LP. min −2x1 −2x2 −5x3 +3x4

s.t. x1 +2x2 +4x3 −x4 +x5 = 6

2x1 +3x2 −x3 +x4 +x6 = 12

x1 +x3 +x4 +x7 = 4

x1, x2, x3, x4, x5, x6, x7 ≥ 0

(a)Is there an optimal solution that is not a vertex? Explain.

(b) If a non-extreme point optimal solution exists, find one.
