ence of two squares DIFFERENCE OF TWO SQUARESThis formula is used to factorise some algebraic expressions. Example 5Solution: | FACTORING THE SUM AND DIFFERENCE OF TWO CUBES The formula for factoring a sum of two cubes is: | x3+y3=(x+y)(x2−xy+y2) | | The formula for factoring a difference of two cubes is: | x3−y3=(x−y)(x2+xy+y2) | | When teaching these factorization methods‚ it may be a good idea to encourage students to know one method for these factorizations rather than have them

The in this unit titled "Patterns" we learned and covered a lot of things. Some of the key concepts we went over are In and Out tables‚ order of operations‚ summation notation‚ consecutive sums‚ conjecture and proof‚ geometry‚ recursive functions‚ positive/negative numbers and algebraic expressions. We used in and out tables to organize data so that we can see patterns. By organizing it and looking at the in then the out it made it easier to find a pattern. Orders of operations were used to correctly

Annamma Thomas Exercise 29 1. The groups were independent because the men and women participating in the experiment did not share any relationships and their quality of life tests were totally independent of one another. 2. The variable described by this number is mental health. Since the P value is .002 and the alpha is .05‚ the difference can cause the null hypothesis to be rejected. 3. The T-Value is significant because the P value is .049 which is the closest to the alpa which is .05

Aryabhata Biography Name While there is a tendency to misspell his name as "Aryabhatta" by analogy with other names having the "bhatta" suffix‚ his name is properly spelled Aryabhata: every astronomical text spells his name thus‚ including Brahmagupta’s references to him "in more than a hundred places by name".Furthermore‚ in most instances "Aryabhatta" does not fit the metre either. Time and place of birth Aryabhata mentions in the Aryabhatiya that it was composed 3‚630 years into the Kali

Significant Figure Rules Significant figure rules are really "rules of thumb" for how to handle the results of calculations so as not to introduce or lose precision in performing a mathematical operation. These rules are not always correct for all situations. However‚ in most cases‚ following the significant figure rules will yield a good result. Rules concerning zero A zero between two significant figures is significant. The number 203.2 consists of four significant figures. A Zero
