Hi, and i apologize for this question, but i tried to look up guides, calculators, and NOTHING can solve this question. and I'm a university student who hasn't done math in over 4 years and i can't remember doing this stuff in highschool :S
Question:
Sadly, i have no idea where to start here, i dont see anything that factors! can a math expert explain how you can factor any algebra question with 2 letters in the middle? or on side. Sorry im asking for too much!x^2 + kx + 10
If i cant get an answer, then maybe a simple link to something that can help with figuring out how to factor with 2 different letters in the middle.
Then when I asked:
you should have done so instead of getting smart:
can only be factorised (with real numbers) if its discriminant is greater than or equal to zero: .
By definition, the discriminant of is .
In your problem, a = 1, b = k and c = 10. Therefore

oh no, this is one serious hard stuff -.-... Im doing a 2nd Year university math course so i can take 3rd year Java & C++ Coding courses.
with questions at the beginning of the semester being this hard, oh my god im going to go threw hell :S
thanks for your awesome answer, i will try to find guides on the internet on how to actually solve for these questions my self.
If you have any reference to anything that would be lovely. Thanks again, and wish you best of luck.
