Question

Simplifique a expressão a seguir:
6ax+2bx-9a-3b
----------------------- =
6a+2b

Answer 1

6ax+2bx-9a-3b   =  2x(3a+b) - 3(3a + b) ==> (2x - 3)(3a + b) ==> 2x - 3
   6a+2b                       2(3a + b )                             2(3a + b)                 2

Answer 2

$\frac{6ax+2bx-9a-3b}{6a+2b} =$

$\frac{2x(3a+b)-3(3a+b)}{2(3a+b)} =$

$\frac{(3a+b)(2x-3)}{2(3a+b)} = \frac{2x-3}{2}$
