If you are to simplify this by multiplying out, use FOIL -- First, Outside, Inside, Last ---

(7x - 4)(2x - 5)

= (7x)(2x) + (7x)(-5) + (-4)(2x) + (-4)(-5)

= 14x² - 35x - 8x + 20

= 14x² - 43x + 20

$$\left({\mathtt{7}}{\mathtt{\,\times\,}}-{\mathtt{4}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}-{\mathtt{5}}\right) = {\mathtt{280}}$$
