Simplify Expressions Calculator

What is the Simplify Expressions Calculator?

The Simplify Expressions Calculator is an intuitive tool designed to simplify mathematical expressions into their simplest forms. Whether you're dealing with algebraic fractions, polynomials, trigonometric identities, or radicals, this calculator provides accurate results with clear, step-by-step explanations. It simplifies even complex-looking expressions quickly, making it a valuable resource for students, teachers, and professionals.

What Does It Mean to Simplify an Expression?

Simplifying an expression means rewriting it in its most compact and simplest form without changing its value. This process involves applying mathematical rules to:

• Combine like terms
• Reduce fractions
• Factor polynomials
• Simplify radicals and exponents
• Use trigonometric identities (e.g., \( \sin^2(x) + \cos^2(x) = 1 \))

For example:

• Expression: \( \frac{x^2 + 4x + 3}{x^2 + 8x + 7} \)
  Simplified: \( \frac{(x + 3)(x + 1)}{(x + 7)(x + 1)} = \frac{x + 3}{x + 7} \)
• Expression: \( 5\cos^2(x) + 5\sin^2(x) \)
  Simplified: \( 5(1) = 5 \) (using the identity \( \cos^2(x) + \sin^2(x) = 1 \))
