===================================

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 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]
