Question

Hey guys. Will you help me find the solution to this function?

g(x)=4x2+8x+2

Fan/medal for help and answer. :)

Answer 1

I can help but no medal please

Answer 2

Okay. :)

Answer 3

but then what will you give?

Answer 4

I'll fan you?

Answer 5

Or I can try to help on anything you may need help with. I'm good at English and Chemistry.

Answer 6

K sounds good
g(x)=0

Answer 7

How'd you get that?

Answer 8

4x2+8x+2 = 0 so 4x^2+4x+2x+2=0
x = -1 or x =-1/2

Answer 9

wait I made a mistake

Answer 10

hate to say this @thisSucks ,,, but u r wrong!!!

Answer 11

u can't factorize that one ....

Answer 12

you could also use the quadratic formula to solve this

Answer 13

u have to use either completing square or the formula

Answer 14

but before that ....
is g(x) = 0 ?

Answer 15

Yeah SURU is right

Answer 16

you have to use the formula

Answer 17

u can't solve g(x) , if g(x) is just an expression...

Answer 18

Completing the square is actually the name of the lesson. All I know is that it will have two irriational solutions due to the rules of discrimnants.

Answer 19

so.... go on with completing square....

Answer 20

Yeah so you can apply the formula there. Sorry I made the mistake :(

Answer 21

let's assume that g(x) = 0 ... Otherwise u won't get any answers...

Answer 22

(2x+2)^2 -2 =0

Answer 23

first step....
\[g(x) =4x ^{2} +8x +2\]

Answer 24

take 4 as common factor... out of the expression

Answer 25

Okay. But what happens with the two?

Answer 26

\[g(x) = 4( x ^{2} + 2x + \frac{ 1 }{ 2 })\]

Answer 27

now... wt is the next step... in ur lesson ?

Answer 28

divide the coefficient of x by 2 and write x and that value of the coefficient as a complete square...
