Multiply and simplify the product. (8 – 5i)2 Select the product. 39 89 39-80i 89-80i

39 - 80i

Step-by-step explanation:

(8 - 5i)²

= (8 - 5i)(8 - 5i)    (expand using FOIL. See attached for reference)

= (8)(8)  + (8)(-5i) + (-5i)(8) + (-5i)(-5i)

= 64 - 40i - 40i + 25i²  

= 64 - 80i  + 25i² (recall that i² = -1)

= 64 - 80i + 25(-1)

= 64 - 80i - 25

= 39 - 80i

i think it is 18

step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
