Question

Find the sum of 5-9i and -4+7i, subtract 14-3i

Answer 1

-13 -i

Explanation:

The first step is to find the sum

5-9i and -4+7i

Add the real parts and then the imaginary parts

5+-4 = 1

-9i + 7i = -2i

5-9i + -4+7i = 1 -2i

Now we subtract 14 -3i

1 -2i - (14 -3i)

Subtract the real parts and then the imaginary parts

1-14 = -13

-2i - -3i = -2i+3i = i

1 -2i - (14 -3i) = -13 -i
