\r
\n" ); document.write( "\n" ); document.write( "\"2h%5E2-h-3=0\" Start with the given equation\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%282h-3%29%28h%2B1%29=0\" Factor the left side (note: if you need help with factoring, check out this solver)\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now set each factor equal to zero:\r
\n" ); document.write( "\n" ); document.write( "\"2h-3=0\" or \"h%2B1=0\" \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"h=3%2F2\" or \"h=-1\" Now solve for h in each case\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So our answer is \r
\n" ); document.write( "\n" ); document.write( " \"h=3%2F2\" or \"h=-1\" \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Notice if we graph \"y=2h%5E2-h-3\" we can see that the roots are \"h=3%2F2\" and \"h=-1\" . So this visually verifies our answer.\r
