Question

Find the separate equation of the line represented by the following equation:

6x2 - 5xy - 6y2 = 0

Sum

Solution

6x2 - 5xy - 6y2 = 0

∴ 6x2 - 9xy + 4xy - 6y2 = 0

∴ 3x (2x - 3y) + 2y(2x - 3y) = 0

∴ (2x - 3y)(3x + 2y) = 0

the separate equations of the lines are

2x - 3y = 0  and  3x + 2y = 0.
