x^2+2x-11=0 ??
\n" ); document.write( "solve each equation by completing the square
\n" ); document.write( "(x^2+2x+1)-11-1=0
\n" ); document.write( "(x+1)^2-12=0
\n" ); document.write( "(x+1)^2=12
\n" ); document.write( "take sqrt of both sides
\n" ); document.write( "x+1=±√12
\n" ); document.write( "x=-1±√12=-1-√12 or -1+√12\r
