Adding Javascript To header

I am trying to add the following javascript code to my header. Each time I add this code right above </head> my website goes blank. Is there a certain place where I'm supposed to be adding this code?
<script type="text/javascript" src="http://www.google.com/jsapi"></script>
<script type="text/javascript">

I am using WP3.0 and lastest Buddypress. I am also using the child theme for BP-Business. I have copied the header from the parent, edited it and placed into the child theme. Then my website goes blank.
Please advise how and where to add javascript to my header. Thank you
