Hi arsey if for 10b I let y=rootx and then solved it from there getting y^2=3/2 then y=root3/2 and then subbed in rootx and squared both sides and lastly getting x=3/2 would I get full marks? y was already used in the question as something else but would I penalised for using it as a way to make the algebra nicer? Also does it matter that I forgot the +- in y=root3/2? Finally, for the inequalities one I used x instead of p and didn't write "or" I just put one inequality under the other would I lose marks for that?
