solve by factoring?
\n" ); document.write( "(x-1)^2 = 7
\n" ); document.write( ":
\n" ); document.write( "(x-1)(x-1) = 7
\n" ); document.write( ":
\n" ); document.write( "x^2 - 2x + 1 = 7
\n" ); document.write( ":
\n" ); document.write( "x^2 - 2x + 1 - 7 = 0
\n" ); document.write( ":
\n" ); document.write( "x^2 - 2x - 6 = 0
\n" ); document.write( ":
\n" ); document.write( "Problem here is, it will not factor.
\n" ); document.write( ":
\n" ); document.write( "solve it by completing the square:
\n" ); document.write( "(x - 1)^2 = 7
\n" ); document.write( "(x - 1) = +/-Sqrt(7)
\n" ); document.write( " x = 1 + Sqrt(7)
\n" ); document.write( "and
\n" ); document.write( " x = 1 - Sqrt(7) \n" ); document.write( "

\n" );
