A useful skill we did in class this week was learning how to “FOIL” polynomials> FOIL is an acronym that stands for the First terms of the brackets, Outside terms, Inside terms, and Last terms of the brackets. In the example, the first step would be to multiply the first terms in each bracket, and y to get . Next is to multiply and 2 (the outside terms) with a product of . Then -5 and y for the inside terms to get -5y. And lastly -5 and 2 for the last terms from each bracket to get -10. Our expression now stands as, and as there are no like terms, we can’s simplify any further.
