A packaging company creates different-sized cardboard boxes. The volume of a box is given by V = 117x^3 – 52x – 351x^2 + 156.

 

a) Determine expressions for the possible dimensions of these boxes.

b) Determine the dimensions and volume of a box if x = 4cm.

We can factor this by finding the GCF of the numbers.

 

=117x3−351x2−52x+156

=13(3x+2)(3x−2)(x−3)
