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

OpenStudy (donblue22):

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

OpenStudy (mwhit2101):

Thought so, just making sure

OpenStudy (freckles):

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

OpenStudy (anonymous):

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.

OpenStudy (mwhit2101):

Thanks guys :)

OpenStudy (freckles):

one more combination for fun the same as c-b+a :p
