Answer:
Solution,
[tex] {(2x)}^{3} - 8 \\ [/tex]
[tex]( {2x)}^{3} - {(2)}^{3} [/tex]
Use the formula:
[tex] {a}^{3} - {b}^{3} = (a + b)( {a}^{2} - ab + {b}^{2} )[/tex]
now,
[tex](2x + 2)( {(2x)}^{2} - 2x \times 2 + {(2)}^{2} )[/tex]
[tex](2x + 2)( {4x}^{2} - 4x + 4)[/tex]
Hope this helps...
Good luck on your assignment...
