\"3m%5E2+%2B+14m+-5=%283m%2Ba%29%28m%2Bb%29\"
\n" ); document.write( "If you FOIL the right hand side, you get,
\n" ); document.write( "\"%283m%2Ba%29%28m%2Bb%29=3m%5E2%2B3bm%2Bam%2Bab\"
\n" ); document.write( "\"%283m%2Ba%29%28m%2Bb%29=3m%5E2%2B%283b%2Ba%29m%2Bab\"
\n" ); document.write( "Comparing to your equation,
\n" ); document.write( "\"3b%2Ba=14\"
\n" ); document.write( "\"ab=-5\"
\n" ); document.write( "Integer factors of 5 are 1 and 5.
\n" ); document.write( "\"+a=1+\", \"+b=-5\"
\n" ); document.write( "\"+a=-1\", \"+b=5\"
\n" ); document.write( "\"+a=5\", \"+b=-1\"
\n" ); document.write( "\"+a=-5\", \"+b=1\"
\n" ); document.write( "All of those combinations solve \"ab=-5\"
\n" ); document.write( "Now check using the other equation to see which one is correct.
\n" ); document.write( "\"+a=1\", \"+b=-5\"
\n" ); document.write( "\"3b%2Ba=14%29%29%29%0D%0A%7B%7B%7B3%28-5%29%2B1=14\"
\n" ); document.write( "\"-14=14\"
\n" ); document.write( "No, next set.
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "\"+a=-1\",\"+b=5\"
\n" ); document.write( "\"3%285%29-1=14\"
\n" ); document.write( "\"14=14\"
\n" ); document.write( "That's the one.
\n" ); document.write( "So then a=-1, b=5.
\n" ); document.write( "\"3m%5E2+%2B+14m+-5=%283m%2Ba%29%28m%2Bb%29\"
\n" ); document.write( "\"3m%5E2+%2B+14m+-5=%283m-1%29%28m%2B5%29\"
\n" ); document.write( "
\n" );
