Factoring polynomials by grouping

Factoring polynomials by grouping

There are a number of ways to factor polynomials, and one of them is by grouping. When using this grouping method, we will need to look for any common factors and then rewrite them as grouped factors.
Basic Concepts: Equivalent expressions of polynomials, Prime factorization, Common factors of polynomials
Related Concepts: Factor by taking out the greatest common factor, Factor by grouping, Factoring difference of squares: x2−y2x^2 - y^2, Factoring trinomials
