Question

4+(1/x)-(1/x^2)=0

Answer 1

what do you want me to do

Answer 2

solve the equation plz

Answer 3

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

Answer 4

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

Answer 5

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?

Answer 6

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

Answer 7

yes plz

Answer 8

and then
3x(x+3)=1

Answer 9

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

Answer 10

then you have 4x^2+x-1

Answer 11

then use the quadratic equation to solve

Answer 12

ok

Answer 13

?

Answer 14

???

Answer 15

hello?

Answer 16

okay bye

Answer 17

hello

Answer 18

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

Answer 19

and for 3x(x+2)=1

Answer 20

hi

Answer 21

sry i thought you left

Answer 22

tell me what you think you would do for that problem

Answer 23

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

Answer 24

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

Answer 25

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

Answer 26

hello?

Answer 27

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

Answer 28

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

Answer 29

Its kicking me off sorry

Answer 30

look above

Answer 31

what grade r u in?

Answer 32

college al why does my grade matter

Answer 33

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

Answer 34

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

Answer 35

high school

Answer 36

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

Answer 37

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

Answer 38

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

Answer 39

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

Answer 40

ok, do you have a graphing calc.?

Answer 41

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

Answer 42

do not
and find a common den

Answer 43

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.

Answer 44

okay. and i would do that by?

Answer 45

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

Answer 46

you should get 4x^2+x-1

Answer 47

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

Answer 48

what is college algebra?

Answer 49

i have never heard of that?

Answer 50

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

Answer 51

thanks for the help

Answer 52

do you want me to finish

Answer 53

alright then you would use the quadratic equation to solve

Answer 54

what's the next question

Answer 55

so the final answer is?

Answer 56

.39 or -.64

Answer 57

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

Answer 58

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

Answer 59

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

Answer 60

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