Answer» Answer: 9x2 - 9(a + b) X + (2a2+ 5ba + 2b2) = 0 9x2 - 9(a + b)x + (2A + b) (a + 2B) = 0 9x2 - 3(2a + b)x - 3 (a + 2b)x + (2a + b) (a + 2b) = 0 3x[3x - (2a + b)] - (a + 2b) [3x - (2a + b)] = 0 [3x - (2a + b)] [3x - (a + 2b)] = 0 x = Step-by-step explanation: 9x2 - 9(a + b) x + (2a2+ 5ba + 2b2) = 0 9x2 - 9(a + b)x + (2a + b) (a + 2b) = 0 9x2 - 3(2a + b)x - 3 (a + 2b)x + (2a + b) (a + 2b) = 0 3x[3x - (2a + b)] - (a + 2b) [3x - (2a + b)] = 0 [3x - (2a + b)] [3x - (a + 2b)] = 0 x = |
