Calculate the following decomposition factor: (2a + b) (2a-3b) - 3A (2a + b) x (x + y) (X-Y) - x (x + y) 2 power

Calculate the following decomposition factor: (2a + b) (2a-3b) - 3A (2a + b) x (x + y) (X-Y) - x (x + y) 2 power

Method 1 (2a + b) (2a-3b) - 3A (2a + b) = 2A (2a-3b) + B (2a-3b) - 6A & sup2; - 3AB = 4A & sup2; - 6ab + 2ab-3b & sup2; - 6A & sup2; - 3AB = - 2A & sup2; - 7ab-3b & sup2; = - (2a + b) (a + 3b) x (x + y) (X-Y) - x (x + y) & sup2; = x (X & sup2; - Y & sup2;) - x (X & sup2; + 2XY + Y & sup2;)
