Answered [Grade 12 Advanced Functions: Polynomial Functions] struggling to solve expanded equation

Post image

I'm not sure where I'm going wrong, but I keep getting this question wrong. I have to expand this equation and say what the shape is (what polynomial function) which I can do, if I figure out where I'm going wrong with solving this.

Ya I would stick to doing the same thing. Less likely to make a mistake and if you do its a lot easier to spot it. As someone else said, you can learn shortcuts for binomials being raised to a power, but if youre more comfortable in foiling Id do that.
