Algebra is also a part of our life‚ we use it on measuring the length of our table‚notebooks‚doors and other more. Another concept of mine is measuring capacity‚In school we always measure the right amount of ingredients that we cook. Because to an culinary student like me we are showing how to measure the exact amount of ingredients that

In all of these equations we are finding the factor for the answer. We are using grouping‚ GCF‚ prime factor‚ and perfect square as well in these set equations. Page 345 - 346 #52. Using (45) as the product and (18) as the sum. 18z + 45 + z^2 Equation (z + 15)(z + 3) Answer Breaking it down using the FOIL method to verify the answer: z * z = z^2 This is a perfect square. 15 * z = 15z z * 3 = 3z 15 * 3 = 45 In this equation to get the answer we need to use the GCF (Greatest Common

INTRODUCTION Abstract Algebra is more rightly considered meta-mathematics than mathematics proper‚ because it can be used to describe the structures that exist within mathematics from a general standpoint. The basic notions of Groups‚ Rings‚ Fields‚ and Algebraic Extensions provide a framework from which to examine almost all of mathematics. These notions serve as unifying concepts that interlace such seemingly disparate subjects as geometry‚ analysis‚ number theory‚ topology and even applied
