$56 x^{2} + 96 x + 40$ $56x^2+96x+40$

Both terms in the second bracket are multiplied by $7 x$ $7x$ and then both are multiplied by $5$ $5$ .

$(7 x + 5) (8 x + 8) = 56 x^{2} + 56 x + 40 x + 40$ $(7x+5)(8x+8)=56x^2+56x+40x+40$

$56 x^{2} + 96 x + 40$ $56x^2+96x+40$

How do you multiply (7x + 5)(8x + 8)(7x+5)(8x+8)(7x + 5)(8x + 8)?
