I have to show that for 2 distinct vectors u and v of a vector space V, for which {u, v} is a basis for V and a and b are nonzero scalars, then {u+v, a*u} is also basis for V.

Please help!

From memory (and common sense), u and v are a basis if they are linearly indep. and they span V right?

So you need to show that provided that u & v satisfy these two conditions, then ([itex]\Rightarrow[/itex]) u+v & a*u also satisfy them.
