what do you want me to do

- anonymous

solve the equation plz

- anonymous

i got x= -1/2 or x= 1/2

or x= -1 +or- root 17/ 8

- anonymous

i got 1 do you mind to check a few others? could you show your work so i can make sure im doing them right?

- anonymous

do you want me to show the work for the one i just did

- anonymous

yes plz

- anonymous

and then
3x(x+3)=1

- anonymous

x^2(4+(1/x)-(1/x^2))=0 gets rid of the denom

- anonymous

then you have 4x^2+x-1

- anonymous

then use the quadratic equation to solve

- anonymous

ok

- anonymous

?

- anonymous

???

- anonymous

hello?

- anonymous

okay bye

- anonymous

hello

- anonymous

sorry it kicked me off. now can you find the real solution for the same equation plz

- anonymous

and for 3x(x+2)=1

- anonymous

hi

- anonymous

sry i thought you left

- anonymous

tell me what you think you would do for that problem

- anonymous

hi would you plz care to answer those 2 ?s only 1 more after that!

- anonymous

well i have that the answer for the problem you just did should be .309 which should be no solution correct? i dont think i worked it right tho

- anonymous

you mean the 3x(x+2)=1

- anonymous

hello?

- anonymous

y do u keep leaving i can't help if u keep doin that

- anonymous

and what would the real solution be for
4+(1/x)-(1/x^2)=0

- anonymous

Its kicking me off sorry

- anonymous

look above

- anonymous

what grade r u in?

- anonymous

college al why does my grade matter

- anonymous

that was solving that equation. not finding the real solution?

- anonymous

it doesn't i just try to get a feel for who im helping

- anonymous

high school

- anonymous

the real solution to any equation, like above with a degree of two it will be quadratic that means that the real solution is any point in which that equation crosses the x-axis or in other words the x-intercepts the term real refers to any solution that can be graphed on a real plane not including imaginary terms or number

- anonymous

or if you are finding a solution to a pair of equations the solution represents the point where the two equations intersect

- anonymous

ok and what would the real solution be for
4+(1/x)-(1/x^2)=0

- anonymous

you haven'y given me any context clues that you are trying to solve two equations intersectio point, that means it will be the x-intercepts

- anonymous

ok, do you have a graphing calc.?

- anonymous

what is the first step in trying to solve that equation?

- anonymous

do not
and find a common den

- anonymous

almost, we have to rationalize the denomintator, because this equation represents a function and only real solutions which can't have a denom. of zero therefore we must get rid of the variables in the denom.

- anonymous

okay. and i would do that by?

- anonymous

mulitply the entire equation on both sides by the largest variable in the denom.

- anonymous

you should get 4x^2+x-1

- anonymous

okay and then?
i just realized we didnt go over this in class. we skiped this section

- anonymous

what is college algebra?

- anonymous

i have never heard of that?

- anonymous

i'm in hs too, that's why i'm asking.

- anonymous

thanks for the help

- anonymous

do you want me to finish

- anonymous

alright then you would use the quadratic equation to solve

- anonymous

what's the next question

- anonymous

so the final answer is?

- anonymous

.39 or -.64

- anonymous

then you check it in the original equation to make sure it works

- anonymous

it works when i checked it, what's the next question

- anonymous

thats all i have now. ive already check the others thanks for all your help

- anonymous

ok, your welcome if you ever need help let me know
