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
