ANSWER:-

  • x−2y−3=0
  • x+y+5=0
  • (x−2y−3)(x+y+5)=0
  • x²  −2xy−3x+xy−2y²  −3y+5−10y−15=0
  •  x² −2y²−xy+2x−13y−15=0

SOLUTION

TO DETERMINE

The combined equation of lines x - 2y = 0 and x + y = 0

EVALUATION

Here the given equation of the lines are

x - 2y = 0 and x + y = 0

Hence the required combined equation of lines is

 \sf (x - 2y)(x + y) = 0

 \sf  \implies x(x + y)  - 2y(x + y)= 0

 \sf  \implies  {x}^{2} + xy - 2xy - 2 {y}^{2}  = 0

 \sf  \implies  {x}^{2}  - xy  - 2 {y}^{2}  = 0

FINAL ANSWER

Hence the required combined equation of the line is

 \sf    {x}^{2}  - xy  - 2 {y}^{2}  = 0
