Hi there,
\n" ); document.write( "Making x the positive number
\n" ); document.write( "x^2 - 3 + 2x = 0
\n" ); document.write( "Rearrange
\n" ); document.write( "x^2 - (2x - 3) = 0
\n" ); document.write( "x^2 - 2x + 3 = 0
\n" ); document.write( "Factorise
\n" ); document.write( "(x + 1)(x - 3) = 0
\n" ); document.write( "x + 1 = 0
\n" ); document.write( "x = -1
\n" ); document.write( "x - 3 = 0
\n" ); document.write( "x = 3 (Disregard as negative)
\n" ); document.write( "x = 3 is the answer.
\n" ); document.write( "Hope this helps :-)
