    you would normally multiply by the square of the denominator \[(x + 2)(x -4) < (x + 2)^2\] because if you multiply by (x + 2) you have \[\frac{(x - 4)}{(x + 2)} \times (x + 2) < 1 \times (x + 2)\] which becomes \[\frac{(x -4)(x+2)}{(x +2)} < (x +2) \] cancel the common factor in the fraction leaves \[(x -4) < (x + 2)\] hope this helps

    well 1 times anything is 1 so 1 times (x + 2) is x + 2
