rewrite this as

x^2-49                 2x

---------       X     --------

x^2-5x-14           x+7

Factor x^2-49 (x+7)(x-7)

Factor x^2-5x-14 (x-7)(x+2)

rewrite the problem as

(x+7)(x-7)          2x

-------------  x    -------

(x-7)(x+2)       (x+7)

x+7 cancels

x-7 cancels

leaving

2x

----

x+2
