AP EAMCET2006MathematicsPair of Lines
The lines represented by the equation x^2-y^2-x+3 y-2=0 are :
Options
- Ax+y-1=0, x-y+2=0
- Bx-y-2=0, x+y+1=0
- Cx+y+2=0, x-y-1=0
- Dx-y+1=0, x+y-2=0
Correct answer
D. x-y+1=0, x+y-2=0
Step-by-step solution
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 The equation of lines which are represented by the given equation, are x-y+1=0 and x+y-2=0 .
