Question 146477
{{{24x^3y-8xy^2}}}
{{{8xy*(3x^2 - y^2)}}}
------------------
{{{(36x^2 - 49y^2)}}}
= (6x - 7y)*(6x  + 7y)
--------------
(x^2 + 5x-24)
= (x + 8)*(x - 3)
------------------
{{{16x^2 - 24xy + 9y^2 }}}
= {{{(4x - 3y)^2}}}
----------------
{{{5r^3 - 5}}}
= {{{5(r^3-1)}}}
= {{{5*(r-1)*(r^2 + r + 1)}}}
