The given expression is:

a. rs(8) - 3 rs(2a^2)

This can be written as:

a. rs(4 * 2) - 3 rs(2) . rs(a^2)

a . rs(4) . rs(2) - 3 rs(2). a

a . 2 . rs(2) - 3a rs(2)

2a rs(2) - 3a rs(2)

Taking a rs(2) as a common factor (or subtracting,since they are like terms) we get:

a rs(2) [ 2 - 3]

==> - a rs(2)

Hence, the solution.
