AP EAMCET · Maths · Pair of Lines
If the slope of one of the lines represented by \(a x^2-6 x y+\) \(y^2=0\) is the square of the other, then the value of \(a\) is
- A \(-27\) 0r \(8\)
- B \(-3\) or \(2\)
- C \(-64\) or \(27\)
- D \(-4\) or \(3\)
Answer & Solution
Correct Answer
(A) \(-27\) 0r \(8\)
Step-by-step Solution
Detailed explanation
Given pair of lines, \(a x^2-6 x y+y^2=0\) Let the slope of one line be \(m\), then slope of another line will be \(m^2\). We know that On cubing Eq. (i) both sides, we get…
