x2 + 8x + 12 = 0

A.
no real solution

B.
one real solution

C.
two rational solutions

D.
two irrational solutions

Answer 1

D right?

Answer 2

do you know the discriminant formula ?

Answer 3

@Mehek14

Answer 4

D not is right sure

Answer 5

Well, I know it is either C or D

Answer 6

what mean rational and irrational ?

Answer 7

I am not sure

Answer 8

so than you need to calculi it - how many will be the discriminant ?

Answer 9

Ummmmmmmmmmm

Answer 10

@Mehek14 do you see it now this asker Only removal tips on what is the right answer and he or she dont know the way how can solving an exercise sure right

Answer 11

Can I ask something?

Answer 12

what is formula of discriminant ?

Answer 13

I don't know but can I ask something?

Answer 14

no you have asked this exercise what you need to solve it

Answer 15

I don't know. Listen, I really don't like how you are handing this. No offense

Answer 16

how you wan solving this exercise than you dont know formula of discriminant ?

Answer 17

I was using Mathway.com but idk what the formula is. I know the answer is -2, -6 though but is that irrantial or rational?

Answer 18

@Abbster2015 i like learn to you how you can solving this exercise but you need learning formula for discriminant first of all - ok. ?

Answer 19

Fine.

Answer 20

so than you dont know this formula of discriminant how you wan solve it ? or you dont learned it again ?

Answer 21

@Qwertty123 Hey jhonny9? I think I am okay. I don't need anymore help.

Answer 22

Thanks for your help though

Answer 23

and again what you have learned when the discriminant is greater than zero and is equal zero and is leas than zero how changing the number of roots of a quadratic ?

Answer 24

Hey, I am okay. But thanks though.

Answer 25

ok.

good luck

bye

Answer 26

Bye :)

Answer 27

Anyone else willing to help me?

Answer 28

I know it's either C or D

Answer 29

I think it is irrational

Answer 30

Still need help?
x^2 +8x+12=0
a=1,b=8, c=12
Triangle=b^2-4ac=8^2-4*1*12=64-48=?

Answer 31

Maybe? Here is my question. Is -2, -6 irrational or ratiioal?

Answer 32

"The sum of a rational number and an irrational number is irrational." By definition, an irrational number in decimal form goes on forever without repeating (a non-repeating, non-terminating decimal). By definition, a rational number in decimal form either terminates or repeats.

Answer 33

I have no clue what that means.

Answer 34

Look at what the definition says!

Answer 35

Oh nevermind. It means rational!

Answer 36

YEAH! okay so what did you get for the Problem?

Answer 37

I ended up getting C as the asnwer

Answer 38

YEAH! :D

Answer 39

Thank you so much!
