Step by step synthetic division, what is the quotient: (2x3 – 2x – 12) ÷ (x – 2) ?

( 2 x³ - 2 x - 12 ) : ( x - 2 ) 

   2   · /  2     0     - 2    - 12
          /         4       8       12
       
             2     4       6        0
    We will multiply 2, 4 and 6 by 2 and add them to the number in the next column.
    Finally:
  q ( x ) = 2 x²  +  4 x + 6

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post

Iagree that is the answer to the question
