Question

ok so im working with imaginary numbers and in this particular equation i have to solve for b.
(3+2i)+(2+bi)=5-4i

Answer 1

how you make calcules with imaginary numbers ?

Answer 2

3+2i +2+bi =

Answer 3

just assum the same terms

Answer 4

im sorry i dont understand what you mean

Answer 5

3+2 = ?
and from 2i and bi what can you factorizing out ?

Answer 6

ok im failing this class so your going to have to break it down further than that luis

Answer 7

yes i like to learn you calcule it step by step if you like it the same too ?

Answer 8

just treat i as any other constant..
3+ 2i + 2 + bi = (3+2) + i(2+b) = 5 -4i

for a+ ib = x+ iy ..we always have a= x and b=y
that is 2 complex no.s are equal if and only if both the real and imaginary parts are equal..
so equate the imaginary parts on both sides and solve for b..

Answer 9

so now you have understood it ?

Answer 10

yes i get it now thank you everyone

Answer 11

ok good luck
