Answer:
1+14i
Step-by-step explanation:
- remove unnecessary parentheses (-3 + 8i) -(-4 - 6i) = -3+8i - (-4-6i)
- when there is a - in front of an expression in parentheses, change the sign of each term in the expression -3+8i+4+6i
- calculate the sum
(-3+4=1) = 1+8i+6i
- collect like terms
(8i+6i=14i) = 1+14i
SOLUTION: 1+14i
