Perform the following operation: $\displaystyle\left[\begin{array}{cc} a &1-a \cr 1+a &-a \cr \end{array}\right] \displaystyle\left[\begin{array}{rrr} -4 &2 &5 \cr 1 &3 &0 \cr \end{array}\right]$

$=$

$\left.\vphantom{\begin{array}{c}\!\strut\\\!\strut\\\!\strut\\\end{array}}\right[$				$\left.\vphantom{\begin{array}{c}\!\strut\\\!\strut\\\!\strut\\\end{array}}\right]$

Note: The entries in the resulting matrix are functions of $a$ .
