Let $\"u=%28w%2B1%29%5E2\"$ ,
\n" ); document.write( " $\"%28w%2B1%29%5E4=48\"$
\n" ); document.write( " $\"u%5E2=48\"$
\n" ); document.write( " $\"u=0+%2B-+sqrt%2848%29\"$
\n" ); document.write( " $\"u=0+%2B-+4%2Asqrt%283%29\"$
\n" ); document.write( " $\"%28w%2B1%29%5E2=0+%2B-+4%2Asqrt%283%29\"$
\n" ); document.write( "Positive solution:
\n" ); document.write( " $\"%28w%2B1%29%5E2=4%2Asqrt%283%29\"$
\n" ); document.write( " $\"w%2B1=0+%2B-+2%2Aroot%284%2C3%29\"$
\n" ); document.write( " $\"+highlight%28w=-1+%2B-+2%2Aroot%284%2C3%29%29\"$
\n" ); document.write( "Negative solution:
\n" ); document.write( " $\"%28w%2B1%29%5E2=-4%2Asqrt%283%29\"$
