You can put this solution on YOUR website!
y + 4x = x^2
\n" ); document.write( "y + x^2 + 8 = 6x
\n" ); document.write( "---------------
\n" ); document.write( "y + 4x = x^2 --> y = x^2 - 4x
\n" ); document.write( "Sub for y into 2nd eqn
\n" ); document.write( "x^2-4x + x^2 + 8 = 6x
\n" ); document.write( "2x^2 - 10x + 8 = 0
\n" ); document.write( "x^2 - 5x + 4 = 0
\n" ); document.write( "(x-4)*(x-1) = 0
\n" ); document.write( "x = 1, x = 4
\n" ); document.write( "-------------
\n" ); document.write( "y = -3, y = 0
\n" ); document.write( "------------
\n" ); document.write( "(1,-3) is an intserction
\n" ); document.write( "(4,0) is another
\n" ); document.write( "
\n" ); document.write( "
\n" );
