Final answer:
Americans wanted to expand into the West for trade and farmland opportunities.
Step-by-step explanation:
Many Americans wanted to expand into the West for several reasons. One reason was to use California for Pacific trade, as it provided access to valuable resources and markets in the Pacific region. Another reason was to find new fertile farmlands, which could support agricultural growth and provide opportunities for economic prosperity. Additionally, there was no evidence to suggest that Americans wanted to learn American Indian farming methods or that they sought to free slaves and give them land as motivations for westward expansion.
