Answer:
587,341
Step-by-step explanation:
(I'm hoping this is what you mean by expand)
(765 – 46)(765 + 46)
First, multiply 765 by 765 = 585,225
Second, multiply 765 by 46 = 35,190
Third, multiply -46 by 765 = -35,190
Fourth, multiply -46 by 46 = -2,116
The second and third answers (35,190 and -35, 190) will cancel each other out. Then, just subtract -2,116 from 585,225.
585,225 - (-2,116) = 585,225 + 2,116 = 587,341
