The width of a rectangle is (x + 2).
if its area is x4 + 2x3 + 6, find its length.

The length of rectangle is given as

Solution:

Given that,

Width of rectangle = x + 2

Area of rectangle =

Length of rectangle = ?

The area of rectangle is given as:

Therefore, length is given as:

Substituting the given values we get,

There are no common factors that could be cancelled. Also numerator cannot be factored further

Thus length of rectangle is given as
