All the Exercises given in the NCERT book in Chapter 9 are included in our algebraic expressions NCERT Class 8 solutions.
Q3. What are algebraic expressions in Class 8?
Ans: In Class 8, algebraic expressions are equations or expressions formed by the combination of variables, numbers and algebraic operations (addition, subtraction, multiplication etc.). An Algebraic expression is a term consisting of variables, coefficients and a constant. For example: 4x + 7y - 2. Here, 4 and 7 are coefficients, x and y are variables, and ‘2’ is a constant. Algebraic expressions are of three types - monomial, binomial, and trinomial.
Q4. What is the formula for algebraic expression?
Ans: Class 8 Maths introduces the concept of algebraic expressions and algebraic identities to the students. Algebraic identities are algebraic equations that are valid for all variable values in them. Following are the formulas for algebraic expressions:
(a+b)2 = a2+2ab +b2
(a-b)2= a2-2ab +b2
(a+b)(a-b)= a2-b2
(x+a)(x+b)= x2+(a+b) x+ab
(x+a)(x-b)= x2+(a-b) x-ab
(x-a)(x+b)= x2+(b-a) x-ab
(x-a)(x-b)= x2-(a+b) x+ab
(a+b)3= a3+3ab(a+b) +b3
(a-b)3= a3-3ab(a-b) -b3
