\n" );
document.write( "y = x^2 +2x - 8  ||factoring (x+4)(x-2) = 0 , x = -4  0r  x = 2 are the solutions
\n" );
document.write( "\"x+=+%28-2+%2B-+sqrt%28+36+%29%29%2F%282%29+\",  x = -1 ± 3
\n" );
document.write( "y = x^2 +2x +1 - 1 - 8  Completing the Square
\n" );
document.write( "y = (x+1)^2 - 9  V(-1,-9) and line of symmetry is x = -1
\n" );
document.write( "and when y  = 0 ⇒   (x+1)^2 = 9, x = -1 ± 3, Pt(2,0) & (-4,0) are the x-intercepts
