    Algebra

    This section explores key algebraic concepts, including linear inequations, quadratic equations, polynomials, ratios, matrices, and progressions.

    Learning Practice

  • 2.1

    Linear Inequations (In One Variable)

    Linear inequations express the inequality between two expressions, and solving these involves finding the values that satisfy the inequality while preserving the inequality signs.

  • 2.2

    Quadratic Equations

    Quadratic equations are mathematical expressions in the form ax² + bx + c = 0 and can be solved using factorization or the quadratic formula.

    Learning Practice

  • 2.3

    Factorisation Of Polynomials

    This section covers the concept of factorising polynomials, essential for simplifying algebraic expressions and solving equations.

    Learning Practice

  • 2.4

    Ratio And Proportion

    This section introduces the concepts of ratio and proportion, focusing on their definitions and practical applications.

    Learning Practice

  • 2.5

    Matrices (Order 2 × 2)

    This section introduces matrices as rectangular arrays of numbers and covers the operations of addition, subtraction, and multiplication specific to 2x2 matrices.

    Learning Practice

  • 2.6

    Arithmetic Progression (A.p.)

    Arithmetic Progression (A.P.) refers to a sequence of numbers where the difference between consecutive terms is constant.
