If α, β are the roots of the equation 2x2 - 3x + 2 = 0, form the equation whose roots are α2, β2 ?
  • a)
    4x2 – x + 4 = 0
  • b)
    2x2 + x + 5 = 0
  • c)
    5x2 + 3x + 7 = 0
  • d)
    6x2 + 4x + 8 = 0
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
If α, β are the roots of the equation 2x2- 3x + 2 = 0, form...
As per the given data
⇒ α + β = - b/a = - ( - 3)/2 = 3/2
⇒ αβ = c/a = 2/2 = 1
For the new equation roots are α2 and β2
∴ sum of the roots α2 + β2 = (α + β)2 - 2αβ = (3/2)2 - 2(1) = 9/4 – 2 = ¼
Product of the roots = α2β2 = (αβ)2 = 12 = 1
⇒ Required equation = x2 – (sum of the roots)x + product of the roots = 0
⇒ x2 – (1/4)x + 1 = 0
⇒ 4x2 - x + 4 = 0
