Well one key difference between the two are that they are different branches or dominations of Christianity, the Mormons not only read the bible but also have another book that they use called the book of Mormon, at one point they had practiced polygamy, the practice and belief you can have more than one wife (only for men of course), and that this belief has been really judged and criticized to a great degree that this belief is scattered in the northern region of the United States. And also at some certain point in the history of Mormonism, the priests had been involved in the occult. Now baptists is another domination of Christianity do not have the same sense of morality nor the same practices and or beliefs as the Mormons, Baptists believe that the 10 commandments of the Lord, were for the israelites back in the old testament, and now since, the sins of mankind are forgiven because of the death and resurrection of Christ those commandments have been diminished, and also eat the food that God has said is unclean. Also services of the Church is held on Sunday, many dominations of Christianity observe Sunday as the sabbath except for the Seventh-day Adventists, who observe Saturday as the sabbath. I hope this helped!
As far as doctrine goes whether there is Baptist, Methodist, or another Christian denomination and Mormon there is a huge difference. A difference that us clearly not able to reconciled by bible based believers.
If you want to know about the Mormon faith, www.mormon.org has a bunch of interesting information. Asking on ask.com will cause you to receive a lot of bias that will cloud your judgement, so if you want a good opinion for yourself it's best to go to the source.
Other than totally different view about God, Jesus Christ, salvation, heaven, he'll, not much. Both teach obedience to the moral teachings of the Bible. But essentially they are diametrically opposed in essential doctrinal truths. Mormonism is not a branch of Christianity; even their own prophets have repeatedly said that. Mormonism denies the diety, resurrection and atonement of Jesus Christ. Without those, there is no Christianity.
