I believe the answer is x^2-4x+1
(I did the problem in my head but it seems correct)
Answer:
5(2x^5 + x^2 - 3)
Step-by-step explanation:
The only factor in common is 5, so you would have 5(2x^5 + x^2 - 3). That can't be factored further. IF the equation had been to the fourth degree on the first term rather than to the fifth degree, it could have been factored as 5(2x^2 -3)(x^2 +1).
It would be 0.3 kg, because 3 times a hundred and divided by a thousand is 0.3.
