Apolynomial has two terms. check all of the factoring methods that should be considered.
- common factor
- difference of cubes
- sum of cubes
- difference of squares
- perfect-square trinomial
- factoring by grouping

Suppose that a polynomial has two terms. Consider following methods and polynomials for which these methods can be applied.

A. Common factor. For example, if a polynomial is of form

where  then you can factor it in the following way

B. Difference of cubes.  For example, if a polynomial is of form

then it can be factored as

C. Sum of cubes.  For example, if a polynomial is of form

then it can be factored as

D. Difference of squares.  For example, if a polynomial is of form

then it can be factored as

E and F methods require more then two terms.

A, B, C and D

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

-2 is the right
