you'll first need to change the content on the actual (live) page

Wait for Googlebot to re-crawl and re-index the page
This is the natural method for how most content is updated at Google. Sometimes it can take a fairly long time, depending on how frequently Googlebot currently crawls the page in question. Once we've re-crawled and re-indexed the page, the old content will usually not be visible as it'll be replaced by the current content. Provided Googlebot is not blocked from crawling the page in question (either by robots.txt or by not being able to access the server properly), you don't have to do anything special for this to take place. It's generally not possible to speed up crawling and indexing, as these processes are fully automated and depend on many external factors.

Use Google's public URL removal tool to request removal of content that has been removed from someone else's webpage
Using this tool, it's necessary to enter the exact URL of the page that has been modified, select the "Content has been removed from the page" option, and then specify one or more words that have been completely removed from that page.

Note that none of the words you enter can appear on the page; even if a word has been removed from one part of the page, your request will be denied if that word still appears on another part of the page. Be sure to choose a word (or words) that no longer appear anywhere on the page. If, in the above example, you removed "top secret velocitus incalculii capturing device," you should submit those words and not something like "my project." However, if the word "top" or "device" still exists anywhere on the page, the request would be denied. To maximize your chances of success, it's often easiest to just enter one word that you're sure no longer appears anywhere on the page.

Once your request has been processed and it's found that the submitted word(s) no longer appear on the page, the search result will no longer show a snippet, nor will the cached page be available. The title and the URL of the page will still be visible, and the entry may still appear in search results for searches related to the content that has been removed (such as searches for [velocitus incalculii]), even if those words no longer appear in the snippet. However, once the page has been re-crawled and re-indexed, the new snippet and cached page can be visible in our search results.

Keep in mind that we will need to verify removal of the word(s) by viewing the page. If the page no longer exists and the server is returning a proper 404 or 410 HTTP result code, making us unable to view the page, you may be better off requesting removal of the page altogether.

Use Google Webmaster Tools URL removal tool to request removal of information on a page from your website
If you have access to the website in question and have verified ownership of it in Google Webmaster Tools, you can use the URL removal tool there (under Site Configuration > Crawler access) to request that the snippet and the cached page be removed until the page has been re-crawled. To use this tool, you only need to submit the exact URL of the page (you won't need to specify any removed words). Once your request has been processed, we'll remove the snippet and the cached page from search results. The title and the URL of the page will still be visible, and the page may also continue to rank in search results for queries related to content that has been removed. After the page has been re-crawled and re-indexed, the search result with an updated snippet and cached page (based on the new content) can be visible.
