AP EAMCET · Maths · Pair of Lines
The lines represented by the equation \(x^2-y^2-x+3 y-2=0\) are :
- A \(x+y-1=0, x-y+2=0\)
- B \(x-y-2=0, x+y+1=0\)
- C \(x+y+2=0, x-y-1=0\)
- D \(x-y+1=0, x+y-2=0\)
Answer & Solution
Correct Answer
(D) \(x-y+1=0, x+y-2=0\)
Step-by-step Solution
Detailed explanation
The equation of pair of straight lines is \(x^2-y^2-x+3 y-2=0\) This equation can be rewritten as \((x-y+1)(x+y-2)=0\) \(\therefore\) The equation of lines which are represented by the given equation, are \(x-y+1=0 \text { and } x+y-2=0 .\)
