Kant’s Metaphysics: The Ideas of Reason
Reason is a faculty of the subject and contains three ideas:
- The I: Makes us think of the only explanation for all knowledge of internal experiences.

Polynomial Factoring Methods Explained
Case I: Common Factor Factoring
Removing the common factor involves identifying the greatest common factor (GCF) shared by all terms in a polynomial (binomial, trinomial, etc.). The GCF consists of the greatest common divisor of the numerical coefficients and the common variables raised to their smallest exponents. Factoring out the GCF simplifies the polynomial.
Common Monomial Factor
This involves finding a single term (monomial) that is a factor of every term in the polynomial.
Common Factor by Grouping
