## Homework Statement

Heres the question I'm tackling:

<b> the height of a prism is x-1, width x-2, length x+3 and the volume is 42cm cubed. Find the dimensions</b>

## Homework Equations

Quadratic formula, common factor, family of functions

## The Attempt at a Solution

I know that 7, 2 and 3 are multiples of 42 but i do not know how to show my work... I have this so far...

42=(x-1)(x-2)(x+3)

42=(x-1)(x^2-x-6)

42=(x^3-x^2-6x-x^2+x+6)

42=(x^3-2x^2-5x+6)

and I do not know if I am doing things right...
