I have to find x and y.
\n" ); document.write( "X squared +2x-8 and y= 2x+1
\n" ); document.write( "-------
\n" ); document.write( "y = x^2 + 2x - 8
\n" ); document.write( "y = 2x+1
\n" ); document.write( "------
\n" ); document.write( "x^2 + 2x -8 = 2x + 1
\n" ); document.write( "------
\n" ); document.write( "x^2 - 9 = 0
\n" ); document.write( "(x-3)(x+3) = 0
\n" ); document.write( "x = 3 or x = -3
\n" ); document.write( "----
\n" ); document.write( "If x = 3, y = 2x+1 = 7
\n" ); document.write( "If x = -3, y = 2x+1 = -5
