You can put this solution on YOUR website!
48x^3 under the radical sign + x (outside of radical) 147x under the radical sign
\n" ); document.write( ":
\n" ); document.write( "Assume you mean:
\n" ); document.write( "SqRt(48x^3) + x*SqRt(147x)
\n" ); document.write( ":
\n" ); document.write( "Factor to find the squares:
\n" ); document.write( "SqRt(16*3*x^2*x) + x*SqRt(49*3*x);
\n" ); document.write( ":
\n" ); document.write( "Extract the squares and you have:
\n" ); document.write( "4x*SqRt(3x) + 7x*SqRt(3x)
\n" ); document.write( ":
\n" ); document.write( "We got SqRt(3) in both expressions so we can add them just like numbers:
\n" ); document.write( "4x*SqRt(3x) + 7x*SqRt(3x) = 11x*SqRt(3x)
\n" ); document.write( ":
\n" ); document.write( "Did this make sense to you?? \n" ); document.write( "

\n" );
