∂L/∂x1 = 8x1 - 4x2 - λ1 - 2λ2 = 0

∂L/∂x2 = 4x2 - 4x1 - λ1 + λ2 = 0

∂L/∂x3 = 2x3 - λ1 - 2λ2 = 0

2x3 = λ1 + 2λ2

∂L/∂ λ1 = x1 + x2 + x3 -15 = 0

x1 + x2 + x3 =15

∂L/∂λ2 = 2x1 - x2 + 2x3 - 20 = 0

2x1 - x2 + 2x3 = 20

∂L/∂x1 = 8x1 - 4x2 - λ1 - 2λ2 = 0

8x1 - 4x2 - (λ1 + 2λ2)  = 0

8x1 - 4x2 - 2x3 = 0
