Question

Is 3x-x^3+7 the same things as -x^3+3x+7?

Answer 1

It is the same because you are still technically subtracting x^3 since there is a negative sign in front of it

Answer 2

Thought so, just making sure

Answer 3

a-b+c is the same as
-b+a+c
-b+c+a
c+a-b
a+c-b
because addition is commutative

Answer 4

Go ahead and pick a value for x, plug it in to both of them, and if you get the same answer with both they are equivalent.

Answer 5
