Question

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

5x2 – 9y2 = 0

Sum
Advertisements

Solution

5x2 – 9y2 = 0

∴ `(sqrt(5)x)^2 - (3y)^2` = 0

∴ `(sqrt(5)x - 3y)(sqrt(5)x + 3y)` = 0

The separate equations of the lines are `(sqrt(5x) + 3y)` = 0 and `(sqrt(5x) - 3y)` = 0.
