The area of a rectangular field is 2c³-c²+6 square units.
If the length of the field is c−2 units, what is its width?
First let's do this simpler one:
The area of a rectangular field is 5 square units.
If the length of the field is 3 units, what is its width?
A = LW
Substitute 5 for A and 3 for L:
5 = 3W
Divide both sides by 3

Answer: The width is
Now let's do yours exactly the same way:
The area of a rectangular field is 2c³-c²+6 square units.
If the length of the field is c−2 units, what is its width?
A = LW
Substitute 2c³-c²+6 for A and c-2 for L:
2c³-c²+6 = (c-2)W
Divide both sides by (c-2)




2c² + 3c + 6
c-2)2c³ - c² + 0c + 6
2c³ -4c²
3c² + 0c
3c² - 6c
6c + 6
6c -12
