$- 2 (- 4 i - 3) (- 4 i - 3) - (5 i - 3) + 10 i - (- 8 i - 6) (- 4 i - 3) - (5 i - 3) + 10 i \overset{◯}{1} - (32 i^{2} + 24 i + 24 i + 18) - (5 i - 3) + 10 i - (32 i^{2} + 48 i + 18) - (5 i - 3) + 10 i - (- 32 + 48 i + 18) - (5 i - 3) + 10 i - (48 i - 14) - (5 i - 3) + 10 i \overset{◯}{2} - 48 i + 14 - (5 i - 3) + 10 i \overset{◯}{3} - 48 i + 14 - 5 i + 3 + 10 i \overset{◯}{4} - 43 i + 17$
①	Multiply each term of $(- 8 i - 6)$ by each term in $(- 4 i - 3)$ . $(- 8 i - 6) \cdot (- 4 i - 3) = 32 i^{2} + 24 i + 24 i + 18$
②	Remove the parentheses by changing the sign of each term within them. $- (48 i - 14) = - 48 i + 14$
③	Remove the parentheses by changing the sign of each term within them. $- (5 i - 3) = - 5 i + 3$
④	Combine like terms: $- 48 i + 14 - 5 i + 3 + 10 i = - 43 i + 17$
