Use properties of the scalar product to prove that for all vectors u,v i have expanded this got the above results, however I dont see how to use properties of the scalar product, i have simply applied some basic algebra?

Stricty speaking is the scalar product of the vector u- v with itself- that's one property of "scalar product". . Another property of the scalar product is that it is commutative- so that . Do the same with .
