Problem:

$\quad\quad\quad \rm{(2 + r) (4 - 2r + {r}^{2} )}$

Solution:

$\quad\quad\quad \green{\rm{(2 + r) (4 - 2r + {r}^{2} )}}$

Step by step solution:

$\quad\quad\quad \color{gold}{\rm{2×4=\boxed{8}}}$

$\quad\quad\quad \color{gold}{\rm{2×(-2r)=\boxed{-4r}}}$

$\quad\quad\quad \color{gold}{\rm{2×{r}^{2}=\boxed{2{r}^{2}}}}$

$\quad\quad\quad \color{gold}{\rm{r×4=\boxed{4r}}}$

$\quad\quad\quad \color{gold}{\rm{r×(-2r)=\boxed{-2{r}^{2}}}}$

$\quad\quad\quad \color{gold}{\rm{r×{r}^{2}=\boxed{{r}^{3}}}}$

Lets get started:

$\quad\quad\quad \color{gold}{\rm{8-4r+2{r}^{2}}}$

$\quad\quad\quad \overline{\color{gold}{\rm{4r-2{r}^{2}+{r}^{3}}}}$

Cancel the like terms:

$\quad\quad\quad \color{gold}{\rm{8\cancel\red{-4r+2{r}^{2}}}}$

$\quad\quad\quad \overline{\color{gold}{\rm{\cancel\red{4r-2{r}^{2}}+{r}^{3}}}}$

$\quad\quad\quad =\color{gold}{\rm{8+{r}^{3}}}$

Answer:

$\quad\quad\quad » \boxed{ \color{gold}{\rm{8+{r}^{3}}}}$

$\color{gold}⟹$ Hence, the answer is $\underline{\red{\rm{8+{r}^{3}}}$ . See my solution and you will get the answer.
