for all other real values a>0
I don’t know the answer I’m sorry god bless you

12 - 3 =9 and -5i+4i=1i or i so it is {9-i}
(4+3)(7-4) if you want the products to multiply each other
4+3(7-4) if you want to use the distributive property and simply have 3 multiplied but the simplification of 7-4 which is 3
