FAQs

Q: What are algebraic expressions in Class 7? A: Algebraic expressions in Class 7 are mathematical expressions that include variables, constants, and arithmetic operations such as addition, subtraction, multiplication, and division.

Q: What is the importance of algebraic expressions in Class 7? A: Algebraic expressions are important in Class 7 as they provide a foundation for solving more complex mathematical problems in the future. They also help in understanding the relationship between different variables and constants and their impact on the outcome of an equation.

Q: How to simplify algebraic expressions in Class 7? A: To simplify algebraic expressions in Class 7, one needs to follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). One should combine like terms and use the distributive property wherever possible.

Q: What are the different types of algebraic expressions in Class 7? A: The different types of algebraic expressions in Class 7 include monomials, binomials, trinomials, and polynomials. Monomials have one term, binomials have two terms, trinomials have three terms, and polynomials have more than three terms.

Q: How to add and subtract algebraic expressions in Class 7? A: To add and subtract algebraic expressions in Class 7, one needs to combine like terms. Like terms are those that have the same variables and exponents. For example, 2x and 3x are like terms, and they can be added to get 5x. One should also pay attention to the signs of the terms, i.e., positive or negative, when adding or subtracting.

Q: How to multiply algebraic expressions in Class 7? A: To multiply algebraic expressions in Class 7, one needs to use the distributive property. The distributive property states that a(b+c) = ab + ac. For example, to multiply 2x by (3x + 4), we can apply the distributive property to get 6x^2 + 8x.

Q: What is factorisation of algebraic expressions in Class 7? A: Factorisation of algebraic expressions in Class 7 is the process of breaking down a polynomial into its factors. For example, the polynomial 6x^2 + 9x can be factored into 3x(2x + 3). Factorisation is useful in simplifying expressions and solving equations.

Q: How to solve algebraic equations in Class 7? A: To solve algebraic equations in Class 7, one needs to isolate the variable on one side of the equation. This can be done by performing the same operation on both sides of the equation to cancel out the constants. For example, to solve 3x + 4 = 7, we can subtract 4 from both sides to get 3x = 3, and then divide by 3 to get x = 1.
