Q: Determine the condition for the lines represented by the equation ax^2 + 2hxy + by^2 = 0 to be perpendicular.
Solution: The lines are perpendicular if the condition a + b = 0 holds true.
Steps: 5
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 perpendicular, the angle between them must be 90 degrees.
Step 3: Recall the condition for two lines represented by a quadratic equation to be perpendicular: it is given by the relationship between the coefficients a, b, and h.
Step 4: The specific condition for the lines to be perpendicular is that the sum of the coefficients a and b must equal zero, which can be written as a + b = 0.
Step 5: Therefore, if you find that a + b = 0, you can conclude that the lines are perpendicular.
