/3x^2 - 3/48x^2 - 2/48x^2 (radical equations)
\n" ); document.write( ":
\n" ); document.write( "Assume you mean:
\n" ); document.write( " $\"sqrt%283x%5E2%29\"$ - $\"3sqrt%2848x%5E2%29\"$ - $\"2sqrt%2848x%5E2%29\"$
\n" ); document.write( ";
\n" ); document.write( " $\"sqrt%2848x%5E2%29\"$ 's are like terms so just do the math:
\n" ); document.write( "you then have;
\n" ); document.write( " $\"sqrt%283x%5E2%29\"$ - $\"5sqrt%2848x%5E2%29\"$
\n" ); document.write( ":
\n" ); document.write( "Factor inside the radicals:
\n" ); document.write( " $\"sqrt%283%2Ax%2Ax%29\"$ - $\"5sqrt%283%2A4%2A4%2Ax%2Ax%29\"$
\n" ); document.write( ":
\n" ); document.write( "Extract the squares:
\n" ); document.write( " $\"x%2Asqrt%283%29\"$ - $\"5%2A4%2Ax%2Asqrt%283%29\"$
\n" ); document.write( ":
\n" ); document.write( " $\"x%2Asqrt%283%29\"$ - $\"20x%2Asqrt%283%29\"$
\n" ); document.write( ":
\n" ); document.write( "Like terms again, do the math and you have
\n" ); document.write( " $\"-19x%2Asqrt%283%29\"$
\n" ); document.write( ":
