Simplify the expression: (1 - 5i) (3 + 7i).

38 + 8i

-32 + 8i

38 - 8i

-32 - 8i

Your answer is 38-8i because what you do is 1 times 3 and get 3 then 1 times 7i and get 7i then you do - 5i times 3 and you get - 15i then - 5i times 7i and you get - 35i2 and the square will cancel out the negative and make it 35 then add that to the 3 and you get 38 then take the - 15i + 7i and get - 8 do your answer is 38-8i
