So please mark this thread [SOLVED]
Hi,
This is probably a relatively easy question, but I've never done this before, and I'm not sure how to go about it.
For the equation find the smallest possible value of such that the equation will have two distinct rational solutions.
Thanks for your help
*Edit - Never-mind. I just figured it out
Hello, Stroodle!
Good for you!For the equation , find the smallest possible value of
such that the equation will have two distinct rational solutions.
Thanks for your help
*Edit - Never-mind. I just figured it out
But is this a trick question?
I noted that it didn't say smallest positive value of .
Using the Quadratic Formula: .
For rational roots, the discriminant must be a square.
This is true for: .
Then the smallest (least) value of is: .
