$\"%282a%29%5E2=24\"$
\n" ); document.write( " $\"sqrt%28%282a%29%5E2%29=sqrt%2824%29\"$
\n" ); document.write( " $\"cross%282%2F2%29a=%280%2B-sqrt%2824%29%29%2F2\"$ Divide both sides by 2
\n" ); document.write( " $\"a=%280%2B-sqrt%2824%29%29%2F2\"$
\n" ); document.write( " $\"a=%280%2B-sqrt%286%29sqrt%284%29%29%2F2\"$ Rewrite the square root with one perfect square as factor
\n" ); document.write( " $\"a=%280%2B-sqrt%286%29%282%29%29%2F2\"$
\n" ); document.write( " $\"a=%280%2B-sqrt%286%29%2Across%282%29%29%2Fcross%282%29\"$ Cancel common terms
\n" ); document.write( " $\"a=0%2B-sqrt%286%29\"$ There's the simplified answer note: ignore the zero. it is only used to make the plus/minus.

\n" ); document.write( "Check:
\n" ); document.write( " $\"%282%28sqrt%286%29%29%29%5E2=24\"$ Plug in $\"sqrt%286%29\"$
\n" ); document.write( " $\"4%2A6=24\"$
\n" ); document.write( " $\"24=24\"$ works
\n" ); document.write( " $\"%282%28-sqrt%286%29%29%29%5E2=24\"$ Plug in $\"-sqrt%286%29\"$
\n" ); document.write( " $\"4%2A6=24\"$
\n" ); document.write( " $\"24=24\"$ works \n" ); document.write( "

\n" );
