    What are [itex]\textbf{u}[/itex] and [itex]\textbf{p}[/itex] supposed to represent? That statement isn't true for two general vectors [itex]\textbf{u}[/itex] and [itex]\textbf{p}[/itex].

    What is the entire problem statement that you are given?

    It has to do with inner product.

    Is that equivalent to <u, p> - <p, p> = <u, p> - [tex]\left\|p\right\|[/tex]2
