Answer:

The factored form of x^3 -1 will be:

[tex]x^3-1^3=\left(x-1\right)\left(x^2+x+1\right)[/tex]

Step-by-step explanation:

Given the expression

[tex]x^3-1[/tex]

Rewrite 1 as 1³

[tex]=x^3-1^3[/tex]

[tex]\mathrm{Apply\:Difference\:of\:Cubes\:Formula:\:}x^3-y^3=\left(x-y\right)\left(x^2+xy+y^2\right)[/tex]

[tex]x^3-1^3=\left(x-1\right)\left(x^2+x+1\right)[/tex]

            [tex]=\left(x-1\right)\left(x^2+x+1\right)[/tex]

Thus, the factored form of x^3 -1 will be:

[tex]x^3-1^3=\left(x-1\right)\left(x^2+x+1\right)[/tex]
