Question
The value of ′a′ for which one root of the quadratic equation
(a2 - 5a + 3) x2 + (3a - 1) x + 2 = 0 is twice as large as the other, is
(a2 - 5a + 3) x2 + (3a - 1) x + 2 = 0 is twice as large as the other, is
Options
A.
B.
C.
D.
Solution
β = 2α
3α =
2α 2 =
⇒ a =
Hence, (A) is the correct answer
3α =
2α 2 =
⇒ a =
