To simplify this expression, we can following the next steps:
First, apply the distributive property:
[tex]8x\text{ + 40 - 4x -16}[/tex]Then, sum similar terms:
[tex]8x-4x\text{ + 40 - 16 = 4x + }24[/tex]Therefore, the simplified expression is
[tex]4x+\text{ 24}[/tex]We can even write the previous expression as
[tex]4(x\text{ + 6)}[/tex]Since 4 is a common factor in the expression.
