Answer:
-7 i + 16
Step-by-step explanation:
Simplify the following:
(-2 i + 1) (5 i + 6)
(1 - 2 i) (6 + 5 i) = (1) (6) + (1) (5 i) + (-2 i) (6) + (-2 i) (5 i):
6 + 5 i - 2 i×6 - 2 i×5 i
-2×6 = -12:
6 + 5 i + -12 i - 2 i×5 i
-2 i×5 i = -2 i^2 5:
6 + 5 i - 12 i + -2 i^2×5
i^2 = -1:
6 + 5 i - 12 i - 2-1×5
-2 (-5) = 10:
6 + 5 i - 12 i + 10
6 + 5 i - 12 i + 10 = (6 + 10) + (5 i - 12 i) = 16 - 7 i:
Answer: -7 i + 16
