For this case we have the following expression:


(5x ^ 2-3x) (8x ^ 2 + 4x)

To find the product, we apply distributive property that states:


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

So:


(5x ^ 2) (8x ^ 2) + (5x ^ 2) (4x) - (3x) (8x ^ 2) - (3x) (4x) =\\40x ^ 4 + 20x ^ 3-24x ^ 3-12x ^ 2 =\\40x ^ 4-4x ^ 3-12x ^ 2

ANswer:


40x ^ 4-4x ^ 3-12x ^ 2
