Why is factoring important in algebra?

Back

Factoring is important because it simplifies expressions and helps solve equations more easily.

What is the first step in factoring by grouping?

Back

The first step is to group the terms of the polynomial into pairs or sets that have common factors.

Factor the expression: 2x^2 + 4x + 3x + 6

Back

(2x^2 + 4x) + (3x + 6) = 2x(x + 2) + 3(x + 2) = (2x + 3)(x + 2)

What does it mean to factor out a common factor?

Back

Factoring out a common factor means to divide each term in a polynomial by the greatest common factor (GCF) and express the polynomial as a product.
