Something I learned this week (oct. 31- nov. 4)

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, (x^2-5)(y+2) the first step would be to multiply the first terms in each bracket, x^2 and y to get x^2y. Next is to multiply x^2 and 2 (the outside terms) with a product of 2x^2. 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, x^2y+2x^2-5y-10 and as there are no like terms, we can’s simplify any further.
