Multiple or divide as indicated 2x/4x+2 x 14 x+7/6

2x/4x+2 x 14 x+7/6 is unclear.  Do you mean 2/4x, or do you mean  2x
                                                                                                             ??
                                                                                                            4x+2
Use parentheses to make things clearer.

I will assume that you meant to write

   2x
* 14x + 7/6
4x + 2

but am very much unsure if this is correct or not.

Perhaps you meant 

2x/(4x+2) times 14(x+7/6)

This comes out as follows:

 2x * 14 (x + 7/6)        28x(x + 7/6)        14x(x + 7/6) 
= =
       4x+2                        2(2x + 1)              2x + 1         after reduction.

Performing the multiplication, we get            14x^2 + 98/6
                                                                     
                                                                              2x+1
  

It appears that you're using "x" both as a variable name and as the "multiply" operator.  If so, please don't!  Use " * " to indicate multiplication.

Please take and share a screen shot of this problem.
