## Inopeki 3 years ago Can someone teach me some algebra?

1. King

algebra is easy ...post ure problems and people can help u.......

2. Inopeki

Yeah but i dont know what "subject" in algebra to learn now... i know linear equations, equations without numbers and i have a basic understanding of the quadratic equation.

3. jhonyy9

what is a discriminant and when you can you us it ?

4. jhonyy9

j

5. FoolForMath

binomial theorem?

6. jhonyy9

just like one example

7. Inopeki

What is binomial theorem?

8. meverett04

Yes we can ...

9. Inopeki

What is a discriminant?

10. jhonyy9

Mimi - so why ?

11. jhonyy9

Inopeki yes

12. Inopeki

jhonyy, i havent learned that. at least not in english.

13. jhonyy9

Inopeki how do you know some algebra ?

14. Inopeki

Are you saying i dont know any algebra?

15. FoolForMath

Binomial theorem is very useful

16. jhonyy9

17. jhonyy9

how do you solve it ?

18. Inopeki

Give me an example and i should be able to solve it.

19. jhonyy9

sorry but i think with 14 years old you not can know this

20. Inopeki

Screw this, Everybody cares too much about my age.. im just gonna go give up and not become a physicist, ok?

21. jhonyy9

pa

22. jhonyy9

pardon for this words but i think that this have learned on 7 or 8 elementary classes

23. jhonyy9

ok for example

24. Inopeki

I can at least try, i got it pretty good yesterday.

25. jhonyy9

\[x ^{2}-3x +2=0\]

26. jhonyy9

solve it

27. Inopeki

Alright.

28. Inopeki

f(x)=x^2-3x+2, am i right so far?

29. jhonyy9

yes

30. jhonyy9

can you do it ?

31. JamesJ

Inopeki, yes that's a perfectly fine piece of notation. Like we all said yesterday, your enthusiasm is fantastic. Why don't you continue to work through the Khan Academy material? The best way to use to this site for mathematics is to come to use with specific questions you have. This is not an ideal place for us to systematically teach you and nearly all of us here aren't here to do that anyway.

32. Inopeki

Wait, i can do this. I did it yesterday with TT.

33. jhonyy9

sorry but this was yesterday and now ?

34. Inopeki

Its a little cloudy, im trying to remember it.

35. jhonyy9

ok and this 3x+6=9 solve for x

36. Inopeki

remove 6 from both sides of =, get 3x=3, divide them both by 3 and you get 1. x=1

37. Inopeki

f(x)=x^2-3x+2, i have to put a number for x right?

38. jhonyy9

nice so 1/(2x) - (3+x)/(x) = 2 solve for x

39. Inopeki

Can you put that in equation form?

40. jhonyy9

- this is in equation form but equation with fractional terms

41. Inopeki

i meant like this, \[blah \div blah\]

42. Inopeki

but something over the other.

43. jhonyy9

how do you assum fractions ?

44. Inopeki

What do you mean`?

45. jhonyy9

1/(2x) - (3+x)/(x) = 2 1 3+x ---- - ----- = 2 2x x

46. jhonyy9

ok ?

47. Inopeki

Awesome.

48. jhonyy9

can you solve it ?

49. Inopeki

Give me some time, i think i can.

50. jhonyy9

so us 1/a - 2/b =c

51. Inopeki

1 3+x ---- - ----- = 2 2x x Nope, im sorry, i cant do this yet. You were right...

52. jhonyy9

ok good luck bye

53. Inopeki

Thanks, ill need it...
