Question

The lines represented by the equation

$ax^{2}(b - c) - xy(ab - bc) + cy^{2}(a - b) = 0$ are

• A. $a(b - c)x - c(a - b)y = 0$, $x + y = 0$
• B. $x + y = 0$, $x - y = 0$
• C. $a(b - c)x - c(a - b)y = 0$, $x - y = 0$
• D. None of these

Answer 1

Answer: (C)

$a(b - c)x - c(a - b)y = 0$, $x - y = 0$

Answer 2

From options, proceed as to find the equation represented by them $a(b - c)x - c(a - b)y = 0$ and $x - y = 0$.
