Factor each expression
Help show me how
(b-c) appears in both terms and can be factored out, giving you
Now note that the second term can also be factored since it is the difference of two perfect squares.
(a^2-16b^2) = (a+4b)(a-4b)
Make that substitution and you will have factored the original expression into three terms.
