3x^2 - 6x = 27
\n" ); document.write( "3x^2-6x-27=0
\n" ); document.write( " Divide by 3
\n" ); document.write( " x^2-2x-9=0
\n" ); document.write( " 〖(x)〗^2-2(x)(1)+〖(1)〗^2-〖(1)〗^2-9=0
\n" ); document.write( " 〖(x-1)〗^2-10=0
\n" ); document.write( " (x-1)^2=10
\n" ); document.write( " x-1=√10
\n" ); document.write( " x-1+1=±√10+1
\n" ); document.write( " X=±3.16+1
\n" ); document.write( " X=4.16: x=-2.16
