\n" );
document.write( "Using the vertex form of a parabola, \"y=a%28x-h%29%5E2+%2Bk\" where(h,k) is the vertex
\n" );
document.write( " y = -3x^2-6x+5            |Completing the square
\n" );
document.write( " y = -3(x+1)^2 + 8         |Vertex is Pt(-1,8)& a Maximum as Parbola opens downward (a< 0) 
\n" );
document.write( " 0 = -3(x+1)^2 + 8     8/3 = (x+1)^2  x = -1 ± 2sqrt(2/3)  {.633, -2.633}
