Did I simplify this expression correctly?
 
            (x - 2) (3x + 5)                                                                             3x                    5    
 
                                                                                                              x     3x^2           5x
          [x + (-2)] (3x + 5) =                                                                    -2    -6x              10
            
          3x + 3x -6x - 10    =
         
          3x^2 - 3x - 10
 
 
Thank you and havea Happy new year
