Unfortunately, the browser used by Answers.com for posting questions is incapable of accepting mathematical symbols. This means that we cannot see the mathematically critical parts of the question. We are, therefore unable to determine what exactly the question is about and so cannot give a proper answer to your question.

A zero of a polynomial function - or of any function, for that matter - is a value of the independent variable (often called "x") for which the function evaluates to zero. In other words, a solution to the equation P(x) = 0. For example, if your polynomial is x2 - x, the corresponding equation is x2 - x = 0. Solutions to this equation - and thus, zeros to the polynomial - are x = 0, and x = 1.
The polynomial is (x + 1)*(x + 1)*(x - 1) = x3 + x2 - x - 1
1+x2 is a polynomial and doesn't have a real root.
y=x2+3 x1=1 x2=2 y(x1) = 1*1+3 = 4 y(x2) = 2*2+3 = 7 x2/x1 = 2, While y2/y1 = 7/4 !=2, and thus the function is nonlinear.
If you mean: x2+3x+2 then it is (x+1)(x+2) when factored

Yes
Both - a polynomial expression, if you like.
1+x2 is a polynomial and doesn't have a real root.
The polynomial equation is x2 - x - 1 = 0.
y=x2+3 x1=1 x2=2 y(x1) = 1*1+3 = 4 y(x2) = 2*2+3 = 7 x2/x1 = 2, While y2/y1 = 7/4 !=2, and thus the function is nonlinear.
x2 -11x-12= (x-12)(x+1)
X2 - X - 2(X + 1)(X - 2)===============(X + 1) is a factor of the above polynomial.
(x + 1) and (x + 2) are monomial factors of the polynomial x2 + 3x + 2 (x + 1) and (x + 3) are monomial factors of the polynomial x2 + 4x + 3 (x + 1) is a common monomial factor of the polynomials x2 + 3x + 2 and x2 + 4x + 3
Find the degree of each term. The greatest degree is the degree of the polynomial. e.g. the degree of x2+x+1 is 2, the degree of x3+x2+x+1 is 3 etc
If you mean: x2+3x+2 then it is (x+1)(x+2) when factored
