\[6x ^{2}-3x+x ^{2}-4x\]

2. twitch

No it just says Simpilfy

3. Davidjohn

you can simplify like terms like x^2 and x's so you can take the 6x^2 + x^2 = 7x^2 because you just add the numbers in front same for the x -3x -4x = ??

Wait can you explain that better Because im Confused on what your asking me

im saying you can only add like terms. you cannot add -3x and x^2, but you can add -3x and -4x. with how 6x^2 +x^2 = 7x^2 is because 6 +1 = 7, and the x^2 stays with the numbers so -4x -3x is the same as (-4-3)*x. so what is -4-3

9. twitch

-1

10. Davidjohn

remember the 4 is negative too

11. twitch

so is it just 1?

12. Davidjohn

and so is the 3

13. Davidjohn

-4, then you take 3 more away from it.

14. Davidjohn

so it goes farther negative

15. twitch

I see

16. Davidjohn

-4-3 is -7, then the x stays with it so the simplification is -7x, and i gave you the 7x^2 the final form is 7x^2 -7x
