Mathematics is a science that helps the world through data. Algebra is the most important and exciting branch in its various branches. In Al Jazeera we use numbers as well as letters (variables) so that different types of questions can be written and solved in general form. This is the place where Algebra formula works. Algebra formula is actually rules or principles that help solve difficult equations in a simple and small way. If a student remembers these formulas well, he can solve the complex mathematical questions properly without wasting more time.
The importance of algebra formula
The importance of Algebra formula in the academic life cannot be ignored. Whenever a student solves mathematical questions, he has to face cases where the use of formulas is essential. For example Square and Cube questions, or two numbers of multiplication and distinction questions. If you do not remember the formulas, it takes more time to solve the questions and often make a mistake. That is why teachers always suggest that Algebra formula be repeated daily so that it is remembered. At the same time, these formulas are needed in practical life, such as engineering, accounts, business and computer science. In this way, we can say that Algebra formula is not just an educational need but the key to success in many areas of life.https://regilia.com/
List of the main algebra formula
Below are some of the most important Algebra formulas that are mostly used in class 8th, 9th and 10th:
- (a+b)2=a2+2ab+b2(a + b)^2 = a^2 + 2ab + b^2(a+b)2=a2+2ab+b2
- (a−b)2=a2−2ab+b2(a – b)^2 = a^2 – 2ab + b^2(a−b)2=a2−2ab+b2
- (a+b)(a−b)=a2−b2(a + b)(a – b) = a^2 – b^2(a+b)(a−b)=a2−b2
- (x+a)(x+b)=x2+(a+b)x+ab(x + a)(x + b) = x^2 + (a + b)x + ab(x+a)(x+b)=x2+(a+b)x+ab
- (a+b)3=a3+3a2b+3ab2+b3(a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3(a+b)3=a3+3a2b+3ab2+b3
- (a−b)3=a3−3a2b+3ab2−b3(a – b)^3 = a^3 – 3a^2b + 3ab^2 – b^3(a−b)3=a3−3a2b+3ab2−b3
- a3+b3=(a+b)(a2−ab+b2)a^3 + b^3 = (a + b)(a^2 – ab + b^2)a3+b3=(a+b)(a2−ab+b2)
- a3−b3=(a−b)(a2+ab+b2)a^3 – b^3 = (a – b)(a^2 + ab + b^2)a3−b3=(a−b)(a2+ab+b2)
- (x+y+z)2=x2+y2+z2+2xy+2yz+2zx(x + y + z)^2 = x^2 + y^2 + z^2 + 2xy + 2yz + 2zx(x+y+z)2=x2+y2+z2+2xy+2yz+2zx
- (x−y−z)2=x2+y2+z2−2xy−2yz+2zx(x – y – z)^2 = x^2 + y^2 + z^2 – 2xy – 2yz + 2zx(x−y−z)2=x2+y2+z2−2xy−2yz+2zx

Conclusion
Finally, it would be fair to say that Algebra formula is the life of mathematics. Without them, mathematics questions seem incomplete. Students who have achieved complete mastery over formulas not only get good numbers in the exams but also succeed in practical life. Therefore, every student should pay special attention to Algebra formula and always keep them in mind.
