x^2+1=-2x
\n" ); document.write( "x^2+2x+1=0
\n" ); document.write( "(x+1)(x+1)=0
\n" ); document.write( ".
\n" ); document.write( "To find 'x', set (x+1) to zero and solve:
\n" ); document.write( "x+1 = 0
\n" ); document.write( "x = -1
\n" ); document.write( ".
\n" ); document.write( "To check, plug back into original equation:
\n" ); document.write( "x^2+1=-2x
\n" ); document.write( "(-1)^2+1=-2(-1)
\n" ); document.write( "1+1 = 2
\n" ); document.write( "2 = 2 (checks)\r
