Best ResponseYou've already chosen the best response.0yep right now combine *like terms \[\huge\rm 2i+93i 6+10i\]

Best ResponseYou've already chosen the best response.0but if i was to distribute to the first part both numbers would be imaginary

Best ResponseYou've already chosen the best response.0there is a plus sign so you don't have to distribute just remove the parentheses

Best ResponseYou've already chosen the best response.0can you help with this problem as well? Write (21 − 4i) − (16 + 7i) + 28i as a complex number in standard form. 5 + 39i 5 + 17i 5 − 39i 5 − 17i

Best ResponseYou've already chosen the best response.0yep they shows what are like terms 3i and 5i are like terms so combine them add their coefficient (3+5)i = 8i

Best ResponseYou've already chosen the best response.0same like last one so what would be the first step ?

Best ResponseYou've already chosen the best response.0okay so this one i would combine right ?

Best ResponseYou've already chosen the best response.0\[ \huge\rm (21 − 4i) \color{ReD}{−} (16 + 7i) + 28i \] there is a negative sign so.?

Best ResponseYou've already chosen the best response.0yes but we have to see where we need then or where we can directly

Best ResponseYou've already chosen the best response.01st step) distribute parentheses by 1 2nd) combine like terms how would you combine them first without applying distributive property ?

Best ResponseYou've already chosen the best response.021 16 would be 5 and it would be subtraction after that right ?

Best ResponseYou've already chosen the best response.0so if you have given with a lengthy Question and then you will still use every basic step huh ?

Best ResponseYou've already chosen the best response.0\(\color{blue}{\text{Originally Posted by}}\) @sohailiftikhar just combine the terms and get answer what is that mean by 1st step and 2nd ? \(\color{blue}{\text{End of Quote}}\) first distribute parentheses

Best ResponseYou've already chosen the best response.0if you start with combining like terms you would get wrong answer

Best ResponseYou've already chosen the best response.0\(\color{blue}{\text{Originally Posted by}}\) @sohailiftikhar yes so it can solve by just adding terms \(\color{blue}{\text{End of Quote}}\) again first we have to distribute the parentheses
