What is the product of (x + 3) (x^2 + 4x +4)
Answer:-
- [tex] \pink{\bold{ {x}^{3} + 7 {x}^{2} + 16x + 12 }}[/tex]
===================================
Solution:-
Use the distributive property then remove the parenthesis and collect the like terms.
- [tex] \pink{\bold{ (x + 3) \times ( {x}^{2} + 4x + 4) }}[/tex]
- [tex] \pink{\bold{ x \times ( {x}^{2} + 4x + 4) + 3( {x}^{2} + 4x + 4) }}[/tex]
- [tex] \pink{\bold{ {x}^{3} + 4 {x}^{2} + 4x + 3 {x}^{2} + 12x + 12 }}[/tex]
- [tex] \pink{\bold{ {x}^{3} + 7 {x}^{2} + 16x + 12 }}[/tex]
Therefore, the product of (x + 3) (x^2 + 4x +4) is [tex] \pink{\boxed{\bold{ {x}^{3} + 7 {x}^{2} + 16x + 12 }}}[/tex].

Step by the Solution
[tex] \huge \color{fuchsia}{ \underline{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }} [/tex]
Step 1
Distribute x² + 4x + 4 onto x + 3
[tex]x \times ( {x}^{2} + 4x + 4) + 3( {x}^{2} + 4x + 4)[/tex]
[tex] \huge \color{maroon}{ \underline{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }} [/tex]
Step 2
Distribute x through the parentheses
[tex] {x}^{3} + 4 {x}^{2} + 4x + 3( {x}^{2} + 4x + 4) [/tex]
Distribute 3 through the parentheses
[tex] {x}^{3} + 4 {x}^{2} + 4x + 3 {x}^{2} + 12x + 12[/tex]
[tex] \huge \color{maroon}{ \underline{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }} [/tex]
Step 3
Collect like terms
[tex] {x}^{3} + 7 {x}^{2} + 4x + 12x + 12[/tex]
Collect like terms
[tex] {x}^{3} + 7 {x}^{2} + 16x + 12[/tex]
