You can put this solution on YOUR website!
f(x)= -2=-3^2+5x
\n" ); document.write( "not -2=-3^2+5x
\n" ); document.write( "but -2=-3x^2+5x
\n" ); document.write( "0=-3x^2+5x+2
\n" ); document.write( "we want factors of -6 that add up to 5
\n" ); document.write( "6 and -1\r
\n" ); document.write( "\n" ); document.write( "0=-3x^2+6x-x+2
\n" ); document.write( "0=-3x*(x-2)-1*(x-2)
\n" ); document.write( "0=-1*(3x+1)*(x-2)
\n" ); document.write( "
\n" ); document.write( "
\n" );
