Question

(5x^2 - 3x + 1)
plus (x^2 - 7) =
minus (6x + 2) =
plus (4x^2 - x + 8) = ?

Answer 1

if i remember right that is a compound equation

Answer 2

no wait a minute why do you put an = sign?

Answer 3

I've gotten so far:

(5x^2 - 3x + 1) + (x^2 - 7)
5x^2(x^2 - 7) = 5x^4 - 35x^2
3x(x^2 - 7) = 3x^3 - 21x
(5x^4 - 35x^2) + (3x^3 - 21x) = ?

Answer 4

It tells us to follow the trails, performing the operations as indicated.

Answer 5

and why at the end you got a ?

And what trails?

Answer 6

I used the question mark to mean I'm not sure what do do next, or what does the problem equal. The trails are each part of the problem. i.e. (5x^2 - 3x + 1) plus (x^2 - 7), like that, then you move on to the next part of the problem, like after you get the answer to (5x^2 - 3x + 1) plus (x^2 - 7) you go ahead and minus it by (6x + 2).

Answer 7

Oh isee :D

Answer 8

Yeah. :)

Answer 9

(5x^2 - 3x + 1)
+ (x^2 - 7) =
-----------------------
6x^2 -3x +1 all i did was add like terms :)
+ -6x - 2) = notice here i took -(6x + 2) and distribute the -
-----------------------
6x^2-9x -1 here i add like terms
+ (4x^2 - x + 8) =
-----------------------------
10x^2-10x+7

Thank you so much!
