Algebraic expressions and identities for Class 8th important formulas
- Algebraic Expressions:
- A variable is a letter or symbol used to represent a value that can change.
- An algebraic expression is a combination of variables, constants, and operations (like addition, subtraction, multiplication, and division).
Examples of algebraic expressions:
- 2x + 3y
- 5a - 2b + 4c
- 3x^2 - 2xy + y^2
- Laws of exponents:
- For any non-zero number a and positive integers m and n:
a^m * a^n = a^(m+n)
a^m / a^n = a^(m-n)
(a^m)^n = a^(m*n)
(ab)^m = a^m * b^m
(a/b)^m = a^m / b^m
- Factorization is the process of expressing a polynomial as a product of simpler polynomials or factors.
- For example, 2x^2 + 6x can be factored as 2x(x+3).
- Simplification is the process of reducing an expression to its simplest form.
- For example, 2x + 3x - 5x can be simplified to 0.
- Linear equations:
- A linear equation is an equation in which the highest power of the variable is 1.
- For example, 2x + 3 = 7 is a linear equation.
- The general form of a linear equation is ax + b = c, where a, b, and c are constants.
- Quadratic equations:
- A quadratic equation is an equation in which the highest power of the variable is 2.
- For example, x^2 + 2x - 3 = 0 is a quadratic equation.
- The general form of a quadratic equation is ax^2 + bx + c = 0, where a, b, and c are constants.
- Formula for area and perimeter of common shapes:
- Area of rectangle = length x width
- Perimeter of rectangle = 2(length + width)
- Area of square = side x side
Q: What is an algebraic expression?
A: An algebraic expression is a combination of constants, variables, and arithmetic operations like addition, subtraction, multiplication, and division. For example, 3x + 2y - 4 is an algebraic expression.
Q: What is a variable in algebraic expressions?
A: A variable is a letter or symbol that represents a number or quantity that can vary or change. For example, in the expression 3x + 2y - 4, x and y are variables.
Q: What is a constant in algebraic expressions?
A: A constant is a fixed number or value in an algebraic expression that does not change. For example, in the expression 3x + 2y - 4, 4 is a constant.
Q: What is an algebraic identity?
A: An algebraic identity is an equation that is true for all values of the variables in the equation. For example, (a + b)^2 = a^2 + 2ab + b^2 is an algebraic identity.
Q: What is the difference between an expression and an equation?
A: An expression is a combination of variables, constants, and arithmetic operations, while an equation is a statement that shows the equality between two expressions. For example, 3x + 2y = 8 is an equation, while 3x + 2y - 4 is an expression.
Q: How can I simplify an algebraic expression?
A: To simplify an algebraic expression, you need to combine like terms, perform the operations in the correct order (parentheses, exponents, multiplication/division, and addition/subtraction), and apply the rules of algebraic identities. For example, to simplify 3x + 2y - x - y + 4z, you combine like terms and get 2x + z.
Q: What are some common algebraic identities?
A: Some common algebraic identities are (a + b)^2 = a^2 + 2ab + b^2, (a - b)^2 = a^2 - 2ab + b^2, and (a + b)(a - b) = a^2 - b^2.
