2x^2
-2x(x + 3)(x + 2)
monomial binomial trinomial polynomial
The expression (x^2 - 22x - 121) is not a trinomial square. A trinomial square is typically in the form ((a - b)^2) or ((a + b)^2), which expands to (a^2 \pm 2ab + b^2). In this case, the expression can be factored into ((x - 11)^2 - 242), indicating it is not a perfect square trinomial.
(x + 2)(x - 9)
-x2 + 2x + 48 = (-x - 6)(x - 8)
It will be difficult to answer this question accurately without knowing "the expression below."
the degree of trinomial is the sum of the variables exponents
-(x + 13)(x - 2)
-(3x - 4)(x - 2)
(x + 5)(x - 8)
aX^2 + bX + c
-2x(x + 3)(x + 2)
(x + 7)(x - 6)
x(x - 1)(x - 13)
It is (x - 9)*(x + 4)
x(x + 5)(x - 7)
x(x - 4)(x - 6)
