Factor each expression
a^2(bc)16b^2(bc)
Help show me how
(bc) appears in both terms and can be factored out, giving you
(bc)(a^216b^2)
Now note that the second term can also be factored since it is the difference of two perfect squares.
(a^216b^2) = (a+4b)(a4b)
Make that substitution and you will have factored the original expression into three terms.
