solve each equation by completing the square
\n" ); document.write( "-3x^2+18x=-30
\n" ); document.write( "3x^2-18x=30
\n" ); document.write( "3(x^2-6x+9)=30+27
\n" ); document.write( "3(x-3)^2=57
\n" ); document.write( "(x-3)^2=57/3
\n" ); document.write( "(x-3)^2=19
\n" ); document.write( "take sqrt of both sides
\n" ); document.write( "x-3=±√19
\n" ); document.write( "..
\n" ); document.write( "x=3+√19
\n" ); document.write( "or
\n" ); document.write( "x=3-√19 \n" ); document.write( "
\n" );
