Hello, I'm currently doing some calculus but my algebra is horrible. Anyway, I'm looking at the solution manual in one of the problems and I don't understand how this expression in one step --> 1 + (0.5x^4 - 0.5x^-4)^2 turns into this expression in the next step --> (0.5x^4 + 0.5x^.4)^2.
Basically what's in the parenthesis goes from a subtraction to a sum (which is what I need for the particular problem, I just don't know why or the steps to get there algebraically step by step). It probably has something to do with the 1 but I don't know how to get rid of the 1.
Thank you so much. Remember, I suck at algebra so step by step explanation would be appreciated.
