I need help with this formula (a+b)(a^2-2ab-b^2) very badly
I need to know if I set it up correctly. I feel as if I may have the signs confused. If I dont, could someone inform me on how to do the negative version of it also?
for reversed signs .... same signs equal positive, different signs equal positive...multiply it out yourself so its ingrained in your head
(a - b)(a 2 + ab + b 2) this is the actual equation that I need help with I just realized.
multiply out, learn sign rules and index rules for multiplication and division.
Would it be (a - b)(a^2 + ab + b^2) always and then the opposite is (a + b)(a^2 - ab + b^2) always?
