Question

If lines represented by 3x^2 - 4xy + a
y^2 = 0 are perpendicular, find value of a​

Answer 1

Answer:

Comparing the equation 3x2 - 4xy - 3y2 = 0 with ax2 + 2hxy + by2 = 0, we get, a = 3, 2h = -4, b = -3. Since a + b = 3 + (- 3) = 0, the lines represented by 3x2 - 4xy - 3y2 = 0 are perpendicular to each other.
