Question

been working that question all weekend it starts as 1/4x^2-2√3x=3 the furthest I can figure is the first step which is to convert to quad equation of 1/4x^2 -2√3x-3=0 now what help!!!

Answer 1

use the formula

Answer 2

and this, this is the Quad form.

Answer 3

I did but cant get rid of the 2√3 at the end and from the multiple choices there is no radical in the end result.

Answer 4

i gav u the decimal ans.

Answer 5

otherwise, solve the value of this in your calc.

Answer 6

LOL Im new where and how please tell me how I care more about the how then answer

Answer 7

OH, Okay!

Answer 8

This is the Quadratic formula.

Answer 9

I know quad but how did you get rid of the 2√3 at the end?

Answer 10

it wont be there in the End.

Answer 11

as u r going to solve it further.

Answer 12

okay first I have 2√3+_ 2√3^2 -4(.25)(3) over 2(.25) right?

Answer 13

answered this on your other post

Answer 14

sorry Im new and havent yet got the hang of navagating this site

Answer 15

can somebody tell me how you arrived at the answer please??? I know quad equation but the 2√3 has me for a loop how do I undo the radical???

Answer 16

thats ok

Since it equals 0, multiply equation by 4
x^2 - 8sqrt3 x -12 = 0
use quadratic formula
x = [8sqrt3 +-sqrt(192+48)] / 2
x = 14.67, -.817

Answer 17

here u go, Rickie. ^.^

Answer 18

Thank you Thank You so much muwahh a weekend mind bender solved MUCHO GRACIAS its not the answer but how is what I need wow thanks so much whew now I can sleep tonite lol..lol

Answer 19

o.O

Answer 20

the 192 comes from squaring (-8sqrt(3))
8*8=64, sqrt3*sqrt3 = 3
64*3 = 192

your welcome

Answer 21

okay but where did the 1/4x^2 go>?

Answer 22

ignore the > symbol lol..lol

Answer 23

1/4 * 4 = 1
i multiplied everything by 4

Answer 24

OH pellet lol..lol.. but why 4? how did you know 4 ( I swear im not a idiot lol please bear with me)

Answer 25

haha
i chose 4 because i wanted to get rid of the fraction
the fraction was 1/4, if you multiply by the denominator it cancels

Answer 26

I am bowing to you right now I get it didnt know you could do that so everything in the equation has to be multiplied by 4 and it evens the playing ground ?

Answer 27

remember when you do this you have to do it to both sides
in this case right side was zero so it didn't change

Answer 28

yep

Answer 29

so the zero stays zero then you work the problem like a radical equation? not a quad equation ? you just started in quad?

Answer 30

well its still a quadratic, just no fraction to worry about
just use the quadratic formula
make sure you plug in the correct a,b,c coefficients

Answer 31

the fact that it has a x^2 term, makes it quadratic

Answer 32

God bless thank you so much♥♥♥♥♥

Answer 33

:)

Answer 34

Im taking Collage Algerbra a sixteen week course in six weeks lol..lol

Answer 35

eventually going for my doctorate in nursing

Answer 36

yeah for summer huh...awesome good luck with that

Answer 37

Thank You have a great one will look for you on here again should I need...Your fantastic not just an answer but a explaination. I hope your a Math Professor♥♥

Answer 38

bye see ya around

Answer 39

haha..aspiring teacher lets put it that way
bye
