Answer:
option a) is correct but their is typing error it sould be x² not x⁴
Step-by-step explanation:
∑α = -2 + 3 + √5 + 3 - √5 = 4
∑αβ = -2(3+√5) + (9-5) + (3-√5) (-2) = -6 -2√5 +4 -6 + 2√5 = - 8
αβγ = -2 (3 +√5) (3 -√5) = -2 (9 -5) = -8
Equation is
x³ - ∑α x² + ∑αβ x - αβγ = 0
x³ - 4x² - 8x + 8 = 0
