You need to categorize the similar terms with the same exponential.
Here, 3 terms can be categorized: x^3, x^2 and constant
Then you simply manipulate the coefficient:
(5-9)x^3 + (-7+4)x^2 + (6+1) = -4x^3 - 3x^2 + 7
Answer:

Step-by-step explanation:
We are given that
Length of flat piece of material=14 in
Width of flat piece of material=6 in
We have to find the volume of box as a function of x.
An open box is made from flat piece of material by cutting equal squares of length x from the corner and folding up the sides.
Therefore, Height of box=x in
Length of box=14-2x in
Width of box=6-2x in
We know that volume of box=
Using the formula
Volume of box=f(x)=
