    It would help if you wrote the original problem correctly. It would also help if you showed YOUR work.

    this is addition right? or is it multiplication? oh man I agree with tkhunny.

    lol at the risk of repeating myself, combine like terms \[-1+6x-4+2x\]

    I think...just a suggestion that if the original poster is typing the equations or questions wrong, we shouldn't go further unless there is more information.

    then imagine that \(x\) is \(i\) it is the same process

    isn't i^2 = -1 ?

    yes, but there is no \(i^2\) in your question think you might be confusing addition and multiplication

    true, but you're just adding and combining like terms for this one

    a typical problem for multiplication would look like this (a+bi)(a-bi) but you don't have that

    for this addition problem your final answer should look like one of these four a+bi,a-bi,ai+b,ai-b
