-(11,14,25) is the correct answer. the two shorter sides must add to a longer distance than the longest side.
Domain (-infinity,infinity)
Min(?
max(2,2)
The given equation is

hence

But x cannot be zero so x=3
So the value of x is 3
h
6x^5 - 30x^4 - 84x^3
we can factor out 6x^3
6x^3(x^2 - 5x - 14)
Also, we can factor x - 7 and x + 2 out of x^2 - 5x - 14
The final answer = 6x^3(x - 7)(x + 2)
