What do you mean doubling? You can add 7+7+7 which equals 21.

For this case we have the following expression:

$(3x + 8) (3x-3)$

We apply distributive property, which by definition establishes that:

$(a + b) (c + d) = ac + ad + bc + bd$

So:

$(3x + 8) (3x-3) =\\9x ^ 2-9x + 24x-24 =\\9x ^ 2 + 15x-24$

Answer:

$9x ^ 2 + 15x-24$
