Study Notes

Algebraic Identities and Polynomials

The product of the sum and difference of two terms x and y is (x + y)(x - y) = x² - y².

Squares of Binomials

The algebraic identity for the square of a binomial (x + y) is (x + y)² = x² + 2xy + y².
The algebraic identity for the square of a binomial (x - y) is (x - y)² = x² - 2xy + y².

Polynomials

A polynomial in one variable is an expression consisting of variables, coefficients, and constants combined using addition, subtraction, and multiplication, but not division.

Variables in Algebra

A variable in algebra is a symbol that represents a value that can change or vary, often represented by letters such as x, y, or z.
