As a binomial it is, surprisingly, x + 3.
It is: x^2 -9
Yes, specifically a binomial.
x + 4
Simply add any multiple of x squared to it.
(x - 5)(x - 8)
It is: x^2 -9
The factors are (x + 6) and (x - 3)
X + 4 is a factor of x^3 + 3x^2 - 10x - 24 along with (x + 2) and (x - 3)
Yes, specifically a binomial.
It is a binomial expression in X and Y.
(x + 10) and (x + 4) are both factors
x + 4
Simply add any multiple of x squared to it.
(x - 5)(x - 8)
(x - 14)(x - 2)
8
x^2 + 6x + 9 cannot be simplified further. If x^2 + 6x + 9 = 0 then we can solve for x. x^2 + 6x + 9 can be broken into a binomial: (x+3)(x+3), which then gives us x = -3.
