What is the condition for the lines represented by ax^2 + 2hxy + by^2 = 0 to be parallel?

What is the condition for the lines represented by ax^2 + 2hxy + by^2 = 0 to be parallel?

Correct Answer: h^2 = ab

Step 1: Understand that the equation ax^2 + 2hxy + by^2 = 0 represents two lines in a plane.
Step 2: Recognize that for two lines to be parallel, they must have the same slope.
Step 3: The condition for the lines to be parallel can be derived from the coefficients of the equation.
Step 4: The condition is given by the formula h^2 = ab, where 'a', 'b', and 'h' are coefficients from the equation.
Step 5: If h^2 equals ab, then the two lines represented by the equation are parallel.
