Homework Help: mat117

Posted by Diana on Tuesday, June 26, 2007 at 11:09pm.

Factor each expression
a^2(b-c)-16b^2(b-c)
Help show me how

(b-c) appears in both terms and can be factored out, giving you
(b-c)(a^2-16b^2)
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.
