Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{ - 2x + 28}}}}}$

Step-by-step explanation:

$\sf{2x + 4(7 - x)}$

Distribute 4 through the parentheses

$\dashrightarrow{ \sf{2x + 28 - 4x}}$

Collect like terms

$\dashrightarrow{ \sf{2x - 4x + 28}}$

$\dashrightarrow{ \sf{ - 2x + 28}}$

Then factor the remains using the difference of cubes: 3x^6(x-4)(x^2+4x+16)
