Since this involves numerous groupings, first thing to observe and to solve is theINNERMOST quantity.

In this case, the innermost quantity is (m+10).

Since you can't simplify that, proceed by removing the quantity.Since the quantity is denoted by a negative sign outside of it, removing the parenthesis you'll have -(m+10) = -m - 10

4m-6{m+4[m-(m+10)+2]} = 4m-6{m+4[m-m-10+2]}

Simplify the new grouping

4m-6{m+4[m-m-10+2]} = 4m-6{m+4[-8]}

Removing the [] sign you'll have

4m-6{m+4[-8]} = 4m-6{m-32}

= 4m -6m + 192

= -2m + 192

------------------------

Therefore the simplified form is

__-2m + 192__
