No it is not, however, 6x² - 5xy is.
If you mean: (2x-7y)(x+y) then it is 2x squared -5xy -7y squared
yes

No because it has 3 terms

Yes, 11 is a monomial, since it only has one term. x, 6x, 5xy and 0.25x5zw2 are all monomials. They are made of numbers and/or variables multiplied together. x + 3 is a binomial because it is made of things which are added or subtracted.

You need at least two terms to find a GCF.
19 x a x a x b = 19a2b
14xy2 would be 3 (14xy)2 would be 4
2,3,2a,3a,3b,2b,3b^2,2b^2
19 x a x a x b = 19a2b
