key notes:<\/p>\n\n\n\n

If a polynomial has four terms, you may be able to factor by grouping. Once the terms are in standard order, factor out the highest common factor (HCF) of the first two terms and the HCF of the second two terms. If the expressions in brackets match, you can factor by grouping:<\/p>\n\n\n\n
