The coefficient.
Yes, because a monomial is one number. 2 to the power of x is still one number. If you had an example such as 2 to the power of x + 3x+ 5, that would be considered a trinomial.
No.
(x - 3)(x - 11)

-- If the last term of the trinomial ... the one that's just a number with no 'x' ... is positive, then both factors have the same sign as the middle term of the trinomial. -- If the last term is negative, then the factors have different signs. If this was never pointed out in class, well, it should have been.
A factor of a perfect square trinomial is eithera number that is a factor of each term of the trinomial,a binomial that is a factor of the trinomial, ora product of the above two.For example, consider 4x2 + 8x + 4It has the factors2 or 4,(x + 1) or2x+2 = 2*(x+1) or 4x+4 = 4*(x+1)
[ x3 + 3x2 + 2x ] is a trinomial. It's factors are [ x, (x + 1), (x + 2) ] .
The sum of p and q
The sum of -p and -q -
The constant term of the trinomial
The sum of -p and -q -
It is the constant term of the trinomial.
It is 1 if the two are the only factors.
-((x + 2)(x - 9))
That's not a trinomial, but it factors to x(x + 19)
The sum of -p and -q -
x2-18x+81 = (x-9)(x-9) when factored
