Question

(x + 2)(x(square)+ x + 1)

Explain it steps

Answer 1

`{x}^(3) + 3 {x}^(2) + 3x + 2`

Explanation:

`(x + 2)( {x}^(2) + x + 1)`

`= x( {x}^(2) + x + 1) + 2( {x}^(2) + x + 1)`

`= {x}^(3) + {x}^(2) + x + 2 {x}^(2) + 2x + 2`

`= {x}^(3) + 3 {x}^(2) + 3x + 2`

Answer 2

x= 2

x= 1-√-3/2

x = 1+√-3/2

Explanation:

(x+2)(x²+x+1) =(x³+x²+x+2x²+2x+2)

(x³+3x²+3x+2)
