Question 58897
simplify {{{(2x+3)(x-4)}}}=?
A lot of people use the acronym FOIL to remember to distribute everything (First, Outer, Inner, Last).  I like to just distribute the first term then distribute the second term in the first parenthesis throught the second parenthesis.
{{{2x(x-4)+3(x-4)}}}
{{{2x(x)+2x(-4)+3(x)+3(-4)}}}
{{{2x^2-8x+3x-12}}}  Combine your like terms:
{{{highlight(2x^2-5x-12)}}}
Happy Calculating!!!
