    What is inside that parentheses is then scalar product (inner product) of those two vectors, the result of which is 4 which then multiplies the rightmost matrix and then this is substracted from the first one.

    In general, if you have two linearly independent vectors u,v\,,\,\,with\,\,\Arrowvert u \Arrowvert^2=<u,u>=1, then v-<u,v>u is an orthogonal vector to u, as can easily be checked (here, <u,v> denotes the inner product of the vectors)
