Solution

The correct option is E if x = y or relationship between x and y cannot be determined
$x^{2} - 18 x + 72 = 0 x^{2} - 12 x - 6 x + 72 = 0 x (x - 12) - 6 (x - 12) = 0 (x - 6) (x - 12) = 0 x = 6, 12 N o w, y^{2} - 15 y + 44 = 0 y^{2} - 11 y - 4 y + 44 = 0 y (y - 11) - 4 (y - 11) = 0 y = 4, 11$
$∴$ Relationship between x and y cannot be determined.
