Question: Find the separate equations of straight lines represented by the following equation: x² - y² + x - y = 0.


Solution:
Given

Single equation of pair of straight lines is
x² - y² + x - y = 0

or, (x +y)(x -y) + 1(x -y) = 0

or, (x -y)(x - y +1) = 0

Hence, the required separate equations of straight lines represented by the above equation is (x - y = 0) and (x - y + 1 = 0).
