RS Aggarwal Solutions Class 7 Maths Chapter 6 – Algebraic Expressions

 


RS Aggarwal Solutions Class 7 Maths Chapter 6 Algebraic Expressions – Overview

  • Addition and Subtraction
  1. Like Terms

The coefficients of all the terms are added or subtracted.

2x + 4x – 3x – 2x = x

  1. Unlike Terms

All the terms with similar variables are taken together and then, the coefficients are added or subtracted.

(2xy – 6xy) + (-3x + 4x) + 5y = -4xy + x + 5y

  • Number Patterns
  1. The successor of a natural number, n = (n+1). Eg: n = 10, so the successor (n+1) = 11.
  2. If n is a natural number, then 2n is an even number.
  3. (2n+1) is an odd number.
  • Algebraic Expression

It is an expression formed with the help of operators i.e addition, subtraction, multiplications, and divisions.

  • Equation

An equation is a condition when an equality sign “=” is used between two expressions.

Example: 4 + 4x = 16.

  • Types Of Algebraic Expressions
  • Monomial Expression – Expression with only one term.

Example: 3xy, 4x², 56y

  • Binomial Expression – Expression with only two terms.

Example: xyz+3y², x²y²+3xy

  • Trinomial Expression – Expression with more than two terms.

Example: xyz+x²y+y²z+z²

  • General Formulae
  1. (a + b)² = a²+ 2ab + b²

  2. (a – b) ² = a² – 2ab + b²

  3. (a + b) (a – b) = a²- b²

  4. (a + b)³ = a³ + b³+ 3ab (a + b)

  5. (a – b) ³ = a³ – b³- 3ab (a – b)

  6. x³ + y³ = (x + y) (x² – xy + y²)

  7. x³ – y³ = (x – y) (x² + xy + y²)
