Questions & Step-by-Step Solutions
Find the condition for the lines represented by the equation ax^2 + 2hxy + by^2 = 0 to be parallel.
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: Recall that the condition for the lines to be parallel can be derived from the coefficients of the equation.
Step 4: The condition for the lines to be parallel is given by the formula h^2 = ab.
Step 5: This means that if you square the value of h and it equals the product of a and b, the lines are parallel.
