Algebraic Equations

Definition

• An algebraic equation is an equation involving variables and coefficients, and is typically expressed in the form of a polynomial equation.
• The variables are represented by letters, and the coefficients are numerical values.

Types of Algebraic Equations

• Linear Equations: Equations in which the highest power of the variable(s) is 1.
  • Example: 2x + 3 = 5
• Quadratic Equations: Equations in which the highest power of the variable(s) is 2.
  • Example: x^2 + 4x + 4 = 0
• Cubic Equations: Equations in which the highest power of the variable(s) is 3.
  • Example: x^3 + 2x^2 - 7x - 12 = 0
• Polynomial Equations: Equations in which the highest power of the variable(s) is a positive integer.
  • Example: x^4 - 3x^2 + 2x - 1 = 0

Properties of Algebraic Equations

• Equivalence: Two equations are equivalent if they have the same solution(s).
• Addition and Subtraction: Equations can be added or subtracted to eliminate variables.
• Multiplication and Division: Equations can be multiplied or divided by a non-zero coefficient to eliminate variables.

Solving Algebraic Equations

• Linear Equations: Can be solved using addition, subtraction, multiplication, and division.
• Quadratic Equations: Can be solved using the quadratic formula: x = (-b ± √(b^2 - 4ac)) / 2a.
• Cubic and Higher-Order Equations: Can be solved using numerical methods, such as the rational root theorem or synthetic division.

Applications of Algebraic Equations

• Modeling Real-World Problems: Algebraic equations can be used to model and solve real-world problems, such as population growth, electrical circuits, and physics.
• Data Analysis: Algebraic equations can be used to analyze and interpret data, such as finding the line of best fit.
