    well you can try expanding each of the options util you get the original expression can you you work out (5x - 2)(x + 1) using the distributive law ?

    well you multiply the second bracket by 5x then by - 2: = 5x(x + 1) - 2(x + 1) can you do that?

    @julianchico - its best not to just give the answer - but to explain how to get the answer - otherwise there is little benefit to the questioner.
