There are different methods. which way did your teacher teach you to use?

OpenStudy (anonymous):

she actually forgot to teach us this method

OpenStudy (anonymous):

she taught us the ones where you add, subtract, and divide but not multiply

OpenStudy (anonymous):

you need to multiply each term by each of the one in the other paran. so 7*4, 7*2i and so on... you understand? afterwards combine like terms
