Greatest Common Factor (GCF)

The greatest common factor (GCF) is the largest number or variable that divides into all terms of an expression without leaving a remainder. It can be found by identifying the highest common factors of the coefficients and variables.

Difference of Squares

The difference of squares is a special factoring pattern: a² - b² = (a + b)(a - b). It involves subtracting two perfect squares, resulting in the product of the sum and difference of the square roots.

Trinomials (x² + bx + c)

Trinomials are expressions with three terms. Factoring trinomials of the form x² + bx + c involves finding two integers that add to b and multiply to c. These integers then become the constants in the binomial factors.

Trinomials (ax² + bx + c)

Trinomials of the form ax² + bx + c can be factored by grouping. To factor them, you need to find two numbers that add up to b and multiply to ac (the product of the first and last coefficients).

Factoring by Grouping

Factoring by grouping is a technique used to factor expressions with four terms. It involves finding two pairs of terms with a common factor and factoring out the common factor of each pair to create a binomial factor.
