Question

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

Explain it steps

Answer 1

Answer:

${x}^{3} + 3 {x}^{2} + 3x + 2$

Step-by-step 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

Answer:

x= 2

x= 1-√-3/2

x = 1+√-3/2

Step-by-step explanation:

(x+2)(x²+x+1) =(x³+x²+x+2x²+2x+2)

(x³+3x²+3x+2)
