If the equation of one asymptote of the hyperbola \(14 x^2+38 x y+20 y^2+x-7 y-91=0\) is \(7 x+5 y-3=0\), then the other asymptote is

  1. A \(2 x-4 y+1=0\)
  2. B \(2 x+4 y+1=0\)
  3. C \(2 x-4 y-1=0\)
  4. D \(2 x+4 y-1=0\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(2 x+4 y+1=0\)

Step-by-step Solution

Detailed explanation

Given hyperbola, On factorising \(14 x^2+38 x y+20 y^2\), we get \[ =(7 x+5 y)(2 x+4 y) \] One of the asymptote is \(7 x+5 y-3=0\) Then, let other asymptote is \(2 x+4 y+k=0\) So, on combining On equating the coefficient of \(x\) from Eqs. (i) and (ii), we get…
