Correct option (c) x2 – 3x + 2 = 0
Explanation:
α2 – 2α + 3 = 0 and β2 – 2β + 3 = 0
α3 – 2α2 + 3α and β3 – 2β2 + 3β
P = α3 – 3α2 + 5α - 2 = 2α2 – 3α - 3α2 + 5α - 2
= α2 – 2α - 2
= 3 - 2 = 1
Similarly, we can show that Q = β3 – β2 + β + 5 = 2
Sum = 1 + 2 = 3 and product = 1 × 2 = 2
Hence x2 – 3x + 2 = 0
