Answer:
use FOIL- Firsts Outsides Insides Lasts
Multiply the -4 and -3 as they are the first numbers of each brackets -4x-3=12
Next the outsides so -4x6i as they are on the outskirts of each brackets -4x6i= -24i
Insides so 3i and -3 as they are in the centre of the two brackets 3ix-3= -9i
Lasts so 3i and 6i as they are at the end of each bracket 3ix6i=18i^2 ( i squared)
add the answers together - 12+-24i+-9i+18i^2= 12-24i-9i+18i^2
Simplify by adding like terms which is -24i and -9i.
12+-33i+18i^2 is the answer
