Let's see.
First, x^2 + 3x - 2 = 0 gives x = (-3 ± √(17))/2, so there already two candidates.
Though, after that, the number of real roots depends on k. Hmm...

sinful plank Jul 2, 2023, 9:53 AM

#

Yeah

#

That's the problem

#

I already did every thing

fringe crest Jul 2, 2023, 9:53 AM

#

Pretty sure there isn't a unique answer, as the roots also depend on k.

sinful plank Jul 2, 2023, 9:53 AM

#

#

I make every possible thing

#

But it failed

fringe crest Jul 2, 2023, 9:54 AM

#

I don't think this problem is formulated correctly. The answer depends on k.

Yes but how we gotta find k

fringe crest Jul 2, 2023, 9:54 AM

#

And the formulas will obviously be very ugly, as is usual with cubic equations.

#

k can be anything, though.

sinful plank Jul 2, 2023, 9:55 AM

#

But how we gonna know it

fringe crest Jul 2, 2023, 9:55 AM

#

We can't know it.

sinful plank Jul 2, 2023, 9:55 AM

#

How should I answer then

fringe crest Jul 2, 2023, 9:55 AM

#

Don't know. As I said, there's probably a mistake.

#

Or some missing data.

sinful plank Jul 2, 2023, 9:56 AM

#

It also say that k must be integer

fringe crest Jul 2, 2023, 9:56 AM

#

Oh...

#

Well, that's pretty important information!

#

You should've said so from the beginning.

#

Not that it helps much, but still.

#

Ok so
