Answer:

[tex]56x^{2}+3x-20[/tex]

Step-by-step explanation:

You can use the FOIL (first, outer, inner, last) to find the answer.

(7x - 4) · (8x + 5) = (7x · 8x) + (7x · 5) + (-4 · 8x) + (-4 * 5)

                          = [tex]56x^{2}+35x-32x-20[/tex]

                           = [tex]56x^{2}+3x-20[/tex]
