Find the vertex and axis of symmerty of y=2X^2+6X
\n" ); document.write( "------------
\n" ); document.write( "Put the equation in vertex form by completing the square:\r
\n" ); document.write( "\n" ); document.write( "2(x^2 + 3x + ? ) = y
\n" ); document.write( "2(x^2 + 3x + (3/2)^2) = y + 2(3/2)^2\r
\n" ); document.write( "\n" ); document.write( "2(x+(3/2))^2 = y + (9/2)\r
\n" ); document.write( "\n" ); document.write( "----------------------------
\n" ); document.write( "Vertex: (-3/2,-9/2)
\n" ); document.write( "Axis of symmetry: x = -3/2
\n" ); document.write( "---------------------------
