  • a)
    a2/bc
  • b)
    c2/ab
  • c)
    b2/ac
  • d)
    None of these

Verified Answer
If m is the ratio of the roots of the equationax2+bx + c =0, then(m +1...
Let ax2 + bx + c = 0  has two roots α and β
Sum of roots α + β = -(b/a)
Product of roots αβ = c/a
So m = α/β then α = mβ
Now substitute this value on the given expressions
Then
