For this case we have the following expression:
[tex](5x ^ 2-3x) (8x ^ 2 + 4x)[/tex]
To find the product, we apply distributive property that states:
[tex](a + b) (c + d) = ac + ad + bc + bd[/tex]
So:
[tex](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[/tex]
ANswer:
[tex]40x ^ 4-4x ^ 3-12x ^ 2[/tex]
