The volume in cubic feet of a box can be expressed as (x) = x^3 - 6x^2 + 8x , or as the product of three linear factors with integer coefficients. The width of the box is x-2. Factor the polynomial to find linear expressions for the height and the length. Show your work.

Answer:

Either the height is [tex]x[/tex] and the length is [tex]x-4[/tex] or the other way round.

Step-by-step explanation:

The volume is given in terms of x as  [tex]V(x)=x^3-6x^2+8x[/tex].

We factor the GCF to get;

[tex]V(x)=x(x^2-6x+8)[/tex].

We split the middle term of the trinomial in the parenthesis.

[tex]V(x)=x(x^2-4x-2x+8)[/tex].

We now factor the expression within the parenthesis by grouping;

[tex]V(x)=x[x(x-4)-2(x-4)][/tex].

[tex]V(x)=x(x-2)(x-4)[/tex].

Since the width of the box is [tex]x-2[/tex] units, the linear expression for the height and length is [tex]x(x-4)[/tex]

Either the height is [tex]x[/tex] and the length is [tex]x-4[/tex] or the other way round.
