Question

Simplify the expression and write your answer in the form of a+bi or a - bi.

(2-7i) - (-6+3i)
a. -4-4i
b. 4+10i
c. -8-10i
d. 4-4i

Answer 1

To simplify the expression (2-7i) - (-6+3i), distribute the negative sign and combine like terms by adding the real and imaginary parts separately.

Step-by-step explanation:

To simplify the expression (2-7i) - (-6+3i), we can distribute the negative sign to each term inside the brackets. This gives us 2 - 7i + 6 - 3i. Next, we combine like terms by adding the real parts (2 + 6 = 8) and adding the imaginary parts (-7i - 3i = -10i). So the simplified expression is 8 - 10i.
