Question 540641
(5x+4)(5x-4)

Multiply each term of first to the second

5x(5x-4)+4(5x-4)
{{{25x^2-20x+20x-16}}}
{{{25x^2-16}}}
----

2x(x+5)+x(3-x)
{{{2x^2+10x+3x-x^2}}}
{{{x^2+13x}}}

-----

{{{5a*b^2*b(7ab^2+3a-4b)}}}

{{{35a^2b^5+15a^2b^3-20ab^4}}}
------------

{{{(5m^2-2mp-6p^2)-2(-3m^2+5mp-p^2) }}}

{{{5m^2-2mp-6p^2+6m^2-10mp+2p^2}}}

{{{11m^2-12mp-4p^2}}}


&This is the only simplifying expression question I have trouble on:
{{{(3x^2y^6)(-4x^2y^6)}}}

{{{-12x^4*y^12}}}
