Please help me with this problem:
\n" ); document.write( "Find the equation of the axis of symmetry and the coordinates of the vertex of the graph of the quadratic function \"y+=+2x%5E2+%2B+2x+-+3.\"
\n" ); document.write( "
Axis of symmetry/x-coordinate of vertex: \"x+=+-+2%2F%282+%2A+2%29\", or \"x+=+-+1%2F2\"
\n" ); document.write( "y-coordinate of vertex: \"2%28-+1%2F2%29%5E2+%2B+2%28-+1%2F2%29+-+3\", or \"2%281%2F4%29+-+1+-+3\", or \"-+3%261%2F2\"
\n" ); document.write( "Coordinates of vertex: (\"-+1%2F2\"\"%22%2C%22\"\"-+3%261%2F2\") \n" ); document.write( "
\n" );
