Aw really say thanks to him and eid mubarak to him too
Btw cheese, am stuck on my maths homework do you know how to factorise this: x^2-3x-xy+3y^2 I did x(x-3)-y(x-3y) But the brackets arent the same that y in there :/
Aw thanks That is the full question, they're asking you to factorise it. Edit:its not fully factorised the brackets arent the same :/ if it was x(x-3)-y(x-3) then i would factorised it as (x-y) (x-3) but there is that y in the second bracket it has to be in double brackets
