the equation kx^2+5x+6 has roots which differ by <1.

Show that 1< k< (25/24)

the equation kx^2+5x+6 has roots which differ by <1.

Show that 1<k<(25/24)

It is meant to say: Show that

 

[hayabusaboston]

It is meant to say show that
1 is less than k is less than 25/24

for some reason its invisible when u type up an inequality LOL

EDIT: heroicpandas has it. Good job.

I dont know what to make the discriminate equal to? or is it a less then or greater than sign?

Neither.

HINT:










Now give it a go yourself.

 

[darlking]

How do you get your writing like that?

 

[hayabusaboston]

Okay I feel as if there is nothing we can give to Sy123 to stump him. he will get absolutely everything lol.

Its called LaTex. Google.

What?

I am only giving a hint to him because it seems like he legitimately wants to attempt the question, so I'm helping out. The 2U forums outside of helping other people is dead. In that it isn't like the 4U forums where people share questions for fun, whereas in the 2U forums that doesn't really happen.

I'm not doing it to prove that I can do the question.

O I didnt mean it like that, I just meant, seeing as though you're giving him a hint, I deduce that its likely you knew what to do instantly, so im just assuming u knew how to do the question immediately. SO yea my comment wasnt directed at this, it was more a generic statement about how its very hard to stump you haha

 

[darlking]

Thanks, im offically a dude now.

 

[darlking]

So can you give me another hint?

 

[hayabusaboston]

Noooooooooooo-oooo, i can't think. This is too much brain power and i dont have that much brain power.

How do you obtain the roots of this quadratic equation?

 

[darlking]

Are you referring to the quadratic equation? or the discriminate?

 

[darlking]

I know both, and the roots are 2 and 3

 

[HeroicPandas]

Hint:Quadratic Polynomials (topic in 2U)

 

[darlking]

I never learnt that. What r u on about. isnt that 3u?
