Multiple choice If (2a + 3b)(2c - 3d)=(2a - 3b)(2c + 3d)Then a/b = c/d a/d = c/b a/b = d/c b/a = c/d none of these Reveal answer Fill a bubble to check yourself A Correct answer Explanation (2a + 3b)(2c - 3d)=(2a - 3b)(2c + 3d)(2a + 3b) / (2a - 3b) = (2c + 3d) / (2c - 3d)4ac -6ad +6bc -9bd = 4ac + 6ad - 6bc - 9bd12bc = 12 adbc = ada/b = c/dHence the option is correct
