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

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.

binomial theorem?
jhonyy9
  • jhonyy9
just like one example

What is binomial theorem?
anonymous
  • anonymous
Yes we can ...

What is a discriminant?
jhonyy9
  • jhonyy9
Mimi - so why ?
jhonyy9
  • jhonyy9
Inopeki yes
anonymous
  • anonymous
jhonyy, i havent learned that. at least not in english.
jhonyy9
  • jhonyy9
Inopeki how do you know some algebra ?
anonymous
  • anonymous
Are you saying i dont know any algebra?
anonymous
  • anonymous
Binomial theorem is very useful
jhonyy9
  • jhonyy9
quadratic equation ???
jhonyy9
  • jhonyy9
how do you solve it ?
anonymous
  • anonymous
Give me an example and i should be able to solve it.
jhonyy9
  • jhonyy9
sorry but i think with 14 years old you not can know this
anonymous
  • anonymous
Screw this, Everybody cares too much about my age.. im just gonna go give up and not become a physicist, ok?
jhonyy9
  • jhonyy9
pa
jhonyy9
  • jhonyy9
pardon for this words but i think that this have learned on 7 or 8 elementary classes
jhonyy9
  • jhonyy9
ok for example
anonymous
  • anonymous
I can at least try, i got it pretty good yesterday.
jhonyy9
  • jhonyy9
\[x ^{2}-3x +2=0\]
jhonyy9
  • jhonyy9
solve it
anonymous
  • anonymous
Alright.
anonymous
  • anonymous
f(x)=x^2-3x+2, am i right so far?
jhonyy9
  • jhonyy9
yes
jhonyy9
  • jhonyy9
can you do it ?

  • 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.

  • anonymous
Wait, i can do this. I did it yesterday with TT.
jhonyy9
  • jhonyy9
sorry but this was yesterday and now ?
anonymous
  • anonymous
Its a little cloudy, im trying to remember it.
jhonyy9
  • jhonyy9
ok and this 3x+6=9 solve for x
anonymous
  • anonymous
remove 6 from both sides of =, get 3x=3, divide them both by 3 and you get 1. x=1
anonymous
  • anonymous
f(x)=x^2-3x+2, i have to put a number for x right?
jhonyy9
  • jhonyy9
nice so 1/(2x) - (3+x)/(x) = 2 solve for x
anonymous
  • anonymous
Can you put that in equation form?
jhonyy9
  • jhonyy9
- this is in equation form but equation with fractional terms
anonymous
  • anonymous
i meant like this, \[blah \div blah\]
anonymous
  • anonymous
but something over the other.
jhonyy9
  • jhonyy9
how do you assum fractions ?
anonymous
  • anonymous
What do you mean`?
jhonyy9
  • jhonyy9
1/(2x) - (3+x)/(x) = 2 1 3+x ---- - ----- = 2 2x x
jhonyy9
  • jhonyy9
ok ?
anonymous
  • anonymous
Awesome.
jhonyy9
  • jhonyy9
can you solve it ?
anonymous
  • anonymous
Give me some time, i think i can.
jhonyy9
  • jhonyy9
so us 1/a - 2/b =c
anonymous
  • anonymous
1 3+x ---- - ----- = 2 2x x Nope, im sorry, i cant do this yet. You were right...
jhonyy9
  • jhonyy9
ok good luck bye
anonymous
  • anonymous
Thanks, ill need it...
