Hi there,
\n" ); document.write( "(x - 2)² -x^2+8=0
\n" ); document.write( "Multiply out bracket.
\n" ); document.write( "(x^2 - 4x + 4) - x^2 + 8 = 0
\n" ); document.write( "Remove brackets.
\n" ); document.write( "x^2 - 4x + 4 - x^2 + 8 = 0
\n" ); document.write( "The x^2 cancel out
\n" ); document.write( "-4x + 4 + 8 = 0
\n" ); document.write( "-4x + 12 = 0
\n" ); document.write( "Move the 12 over to the other side
\n" ); document.write( "remembering to change the sign.
\n" ); document.write( "-4x = -12
\n" ); document.write( "Divide both sides by -4
\n" ); document.write( "x = -12/-4
\n" ); document.write( "x = 3.
\n" ); document.write( "Hope this helps :-)
