Question

What is the value of (-7 + 3i) - (2-6i)?

Answer 1

Answer:

9 (i - 1)

Step-by-step explanation:

Simplify the following:

-7 + 3 i - (-6 i + 2)

-(2 - 6 i) = -2 + 6 i:

6 i - 2 - 7 + 3 i

-2 + 6 i - 7 + 3 i = (6 i + 3 i) + (-2 - 7) = -9 + 9 i:

9 i - 9

Factor 9 out of 9 i - 9 giving 9 (i - 1):

Answer:  9 (i - 1)

Answer 2

Answer:

-9 + 9i

Step-by-step explanation:

$(-7+3i)-(2-6i)\\\\=-7+3i-2-(-6i)\\\\=(-7-2)+(3i+6i)\\\\=-9+9i$
