  • Simplifying algebraic expressions
  • Solving inequalities
  • Working with logarithmic and exponential functions
  • Finding roots and intercepts
  • Evaluating complex number expressions

The calculator uses symbolic computation to provide step-by-step and exact solutions, helping users understand the reasoning behind the results.

How the Algebra 2 Calculator Works

The calculator is powered by algebraic solving algorithms based on fundamental mathematical principles. It accepts an algebraic expression or equation as input and performs symbolic manipulation to provide the desired output.

Here are the main processes involved:

  1. Input Interpretation:
    The tool reads and interprets your algebraic expression, identifying constants, variables, and operations.
  2. Simplification or Solution:
    Depending on your request (simplify, solve, factorize, etc.), the calculator applies appropriate algebraic rules.
  3. Output Generation:
    The result is displayed instantly, showing simplified forms or complete step-by-step solutions.

Key Formulas Used in Algebra 2

Here are some essential formulas commonly used by the Algebra 2 Calculator:

  1. Quadratic Formula:
    x = (-b ± √(b² – 4ac)) / 2a
  2. Slope Formula:
    m = (y₂ – y₁) / (x₂ – x₁)
  3. Distance Formula:
    D = √((x₂ – x₁)² + (y₂ – y₁)²)
  4. Midpoint Formula:
    M = ((x₁ + x₂)/2, (y₁ + y₂)/2)
  5. Exponential Function:
    y = a * e^(bx)
  6. Logarithmic Function:
    y = logₐ(x) = ln(x) / ln(a)
  7. Polynomial Factoring:
    ax² + bx + c = a(x – r₁)(x – r₂)

These equations are the foundation for solving most Algebra 2-level problems.

Example Calculations

Example 1 – Solving a Quadratic Equation

Problem: Solve 2x² + 3x – 5 = 0

Using the formula:
x = (-b ± √(b² – 4ac)) / 2a
Here, a = 2, b = 3, c = -5

x = (-3 ± √(9 + 40)) / 4
x = (-3 ± √49) / 4
x = (-3 ± 7) / 4

x₁ = 1, x₂ = -2.5

Result: x = 1 or x = -2.5

Example 2 – Simplifying an Expression

Problem: Simplify 3x² + 4x – 5x² + 7

Combine like terms:
(3x² – 5x²) + 4x + 7 = -2x² + 4x + 7

Result: -2x² + 4x + 7

Example 3 – Factoring a Polynomial

Problem: Factorize x² – 5x + 6

Find two numbers that multiply to +6 and add to -5: (-2, -3)

Result: (x – 2)(x – 3)

Example 4 – Solving a System of Equations

x + y = 6
x – y = 2

Add the two equations: 2x = 8 → x = 4
Substitute back: 4 + y = 6 → y = 2

Result: x = 4, y = 2
