## anonymous one year ago How do you combine like terms? Can you give an example?

@Zale101

2. anonymous

wait combining like terms tell me a equation

3. anonymous

um..12+3x+2x2=5x-1

4. anonymous

2x2?

5. anonymous

is that a multiplication sign or x

6. anonymous

no its this $2 \times ^{2}$

7. anonymous

12+3x+2x squared =5x-1 ok

8. anonymous

so in this case there would not be any like terms ,do you want to solve this problem?

9. anonymous

can you just tell me how to combine like terms

10. anonymous

Here an example problem : 5x+2x-3+7=5-2x ok

11. anonymous

Like terms would be 5c,2x,-2x but you can combine -2x with the 5x and 2x because there not on the same side.ok

12. anonymous

5x not 5c PS

13. anonymous

ok do you know what like terms are

14. anonymous

yes

15. anonymous

so basically in this equation 5x+4x=-x+10 Like terms would be 5x,4x,-x ok?

16. anonymous

ok

17. anonymous

combining like terms is different ok you can only combine terms with the same coefficient

18. anonymous

19. anonymous

so like 5x-3x+7x+4x-2+5=6+9 you can not combine like terms from numbers from the other side

21. anonymous

got that

22. anonymous

yes

23. anonymous

ok to combine terms this is how you would do it i will give multiple examples ok?

24. anonymous

ok

25. anonymous

|dw:1442988004108:dw|

26. anonymous

now get it

27. anonymous

so can you give me a brief summary on how you combine like terms in words though please :)

28. anonymous

you can only combine like terms if they have the same exponents,or same terms like 5x can combine with 5x but cant combine with 5xsquared

29. anonymous

Do you know how to combine like terms tho

30. anonymous

kinda

31. anonymous

ok i got a video after ask me what questions you have ok?

32. anonymous

hello?

33. anonymous

yes

34. anonymous
35. anonymous

you never gave me a brief summary on how to combine like terms in words

36. anonymous

37. anonymous

ok done watching the video

38. anonymous

hello

39. anonymous

yes

40. anonymous

ok now u get it

41. anonymous

yes but i want you to describe it to me in words

42. anonymous

In short words its simplifying the equation by taking same variables which could have any value and writing it in a short version

43. anonymous

better now

44. anonymous

now what are smart cents??

45. anonymous

Hello??????

46. anonymous

hello!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

47. anonymous

yes

48. anonymous

thank you for your help.. im done with the question :) bye

49. anonymous

-_- were you go

50. anonymous

51. anonymous

yes

$4-a+x^2+5y+3a-x^2+6y+y^2+100$rearranging$=4+100-a+3a+x^2-x^2+5y+6y+y^2$ (factoring and) combining the like terms$=(4+100)+(-1+3)a+(1-1)x^2+(5+6)y+y^2$$=104+2a+11y+y^2$
