This is an quadratic equation.
\n" ); document.write( "we can solve it by either factoring it or using the quadratic formula.\r
\n" ); document.write( "\n" ); document.write( "BY FACTORING:
\n" ); document.write( "6n^2 - 19n + 15 = 0
\n" ); document.write( "(2n - 3)(3n - 5) = 0
\n" ); document.write( "So
\n" ); document.write( "n = 3/2 or n = 5/3\r
\n" ); document.write( "\n" ); document.write( "BY USING THE QUADRATIC FORMULA
\n" ); document.write( "here a = 6, b = -19 and c = 15
\n" ); document.write( "Substituting into the formula:
\n" ); document.write( "\"n+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
\n" ); document.write( "we have
\n" ); document.write( "\"n+=+%28-%28-19%29+%2B-+sqrt%28+%28-19%29%5E2-4%2A6%2A15+%29%29%2F%282%2A6%29+\"
\n" ); document.write( "\"n+=+%28-%28-19%29+%2B-+sqrt%28+1+%29%29%2F%282%2A6%29+\"
\n" ); document.write( "\"n+=+%28-%28-19%29+%2B-+1%29%2F%282%2A6%29+\"
\n" ); document.write( "n = (19 + 1)/12 = 5/3 or
\n" ); document.write( "n = (19 - 1)/12 = 3/2
\n" ); document.write( " \n" ); document.write( "
\n" );
