Concepts Learning Sessions
Before delving into the concepts of Linear Equations in two variables, its important to revisit the basics of Algebra - terms, expressions and
definition and types of Polynomials. In this session following topics have been covered:
- Terms and Expressions
- Polynomials and their types
- Linear Polynomials
- Linear Equations in two variables
- Why is a Linear Equation called so?
- Meaning of solution of a Linear Equation
- A pair of Linear Equations
- Methods of Solving a pair of Linear Equations.
- Graphical Method
- Algebraic Method : (Methods of Substitution and Elimination have been discussed in this session)
In this session, a small introduction to Determinants has been made. Cramer's Rule to solve a system of linear equations require the knowledge of Determinants and the method of finding its value. This session would not be sufficient for in-depth knowledge in Determinants.
In this session, a method of solving a pair of linear equations in two variables using Cramer's Rule has been described.
