So you need to solve the inequality
Can you solve this inequality (so the answer will be in terms of interval)
Hi, we've been studying polynomials at college recently and we've covered a lot of topics on it, but I'm stuck on one question. I remember doing questions like it, but we've gone over so much in the meantime that I've forgotten how to work it out!
Find the set of values of k such that the equation has two distinct roots.
The discriminant (4k squared - 4(1)(3k)) has to be > 0 for it to have 2 distinct roots, but I forgot how to work it out!
Any tips? Thanks =D
Is it ?
Because don't you make each of the brackets equal 0 to find the intervals, so the brackets (4k)(4k - 3) would mean k would be > 0 and > 3/4
I think I'm totally off, but I tried k as 0.74 and it didn't give a positive number, but 0.76 does, so it seems right...
