You can put this solution on YOUR website!
x^2-(3x+4)=(x+8)(x-5)
\n" ); document.write( "First use foil
\n" ); document.write( "x^2-(3x+4)=x^2-5x+8x-40
\n" ); document.write( "then combine like terms
\n" ); document.write( "x^2-3x-4=x^2+3x-40
\n" ); document.write( "now move all x's to one side of the
\n" ); document.write( "equation and regular numbers to the other
\n" ); document.write( "to make an equation.
\n" ); document.write( "x^2-x^2-3x-3x=-40+4
\n" ); document.write( "now add or subtract like terms
\n" ); document.write( "-9x=-36
\n" ); document.write( "now divide -9 to both sides
\n" ); document.write( "-9x/-9=-36/-9
\n" ); document.write( "x=4\r
\n" ); document.write( "\n" ); document.write( "good luck!!!
