Hello there,

Well we are given with 3(x + 4)² and we need to simplify this expression...

  1. write out the expression: 3(x + 4)(x + 4)
  2. then we distribute the parentese: 3(x² +4x +4x +16)
  3. combine like terms: 3(x² + 8x + 16)
  4. distribute the 3 in the parentese: 3x² + 24x + 48

So another way to express this would be 3x² + 24x + 48.

Hope I helped,

Amna
