No, it's not a binomial. (x + 5) is an example of a binomial. A binomial has more than one term. Just look at the word binomial and you will know why. Bi means two.2xy is a monomial. Mono means one.
Neither of those expressions is a binomial. [ 2y + 2xy ] is a binomial.
Monomial.
(x + y)2 = x2 + 2xy + y2
√18xy = √(9*2xy) = √9*√2xy = 3*√(2xy)
4xy - 2xy

2xy
(2xy)x=2x2y
Since 2xy is a factor of 2x2y, it is automatically the GCF.
2xy + 6xy = 8xy
(x + 4y)(x - 6y)
√18xy = √(9*2xy) = √9*√2xy = 3*√(2xy)
The three terms are: -3xy2, 2xy and -4y3
4xy - 2xy
3xy and 2xy. You can see that 3xy and 2xy have something in common with each other. They both have xy and the end of them. Hope this helped.
