document.write( "write each function in vertex form by completing the square:
\n" );
document.write( "  the vertex form of a parabola,  where(h,k) is the vertex
\n" );
document.write( "1. y= x^2 + 4x  = (x+2)^2 - 4                  
\n" );
document.write( "2. y = 2x^2 + 8x + 3 = 2(x+2)^2 -8 + 3 = 2(x+2)^2 - 5

document.write( "3. y = -2x^2 -8x = -2(x+2)^2 + 8
\n" );
document.write( "4. y = -x^2 + 4x + 4 = -(x-2)^2 + 4 + 4 = x(x-2)^2 + 8
