When you want to indicate raising to a power use the caret mark ^


2k^3 + 3k^2 + 6k + 9


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2k^3\ +\ 3k^2\ +\ 6k\ +\ 9]


Rearrange:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2k^3\ +\ 6k\ +\ 3k^2\ +\ 9]


Take 2k out of the first two terms and 3 out of the second two terms:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2k(k^2\ +\ 3)\ +\ 3(k^2\ +\ 3)]


Take *[tex \Large k^2\ +\ 3] out of each term


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (2k\ +\ 3)(k^2\ +\ 3)]
