Question

Q5. Show that the lines represented by photo are coincident.​

Answer 1

Answer:

${x}^{2} + 6xy + 9 {y}^{2} = 0 \\ \\ {(x)}^{2} + 2 \times x \times 3y + {(3y)}^{2} = 0 \\ \\ {(x + 3y)}^{2} = 0$

Answer 2

Step-by-step explanation:

${x}^{2} + 6xy + 9 {y}^{2} = 0 \\ {x}^{2} + 2 \times x \times (3y) + {(3y)}^{2} = 0 \\ {(x + 3y)}^{2} = 0$

so,

$x + 3y = 0 \: \: \: \: or \: \: x + 3y = 0$

i.e lines are coincident.
