4x^2+20x+5y+xy

*you have top factor by grouping.If you need more info just ask me but please help me!!!*

An example from http://www.ltcconline.net/greenl/courses/152b/FactoringRatExpr/factor.htm

Factoring by Grouping

Consider the expression

3x2 + 6x - 4x - 8

We can factor this by grouping two at a time:

(3x2 + 6x) - (4x + 8)

We now pull out the GCF of each:

3x (x + 2) - 4 (x + 2)

Pull out the GCF again:

(3x - 4) (x + 2)
