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?

1) The area of the rectangular field is 2c^3 - c^2 + 6

2) The length is c - 2

3) Divide the area by the length to obtain the width:

   2c^3 - c^2 +           6    | c - 2
                                      
 -2c^3 + 4c^2                    2c^2 + 3c + 6

             3c^2 +         6
            -3c^2 + 6c
          
                        6c + 6
                       -6c + 12
                     
                               18

Given that the division is not exact (the residue is 18) you cannot determine an exact width.

So, I guess ther is a mistake in some of the given expressions. Just use the right expressions and use this procedure to get the answer.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
