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

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
