meso (meso@the.asbestos.cafe)'s status on Monday, 13-Nov-2023 11:23:55 JST meso @dushman @hidden @lizzie @theorytoe sorry i forgot to say the thing i tagged you about. Can you explain quadratic equations and why ax2+bx+c=0 makes sense. and like, what is D=b2-4ac. What the fuck is this. then why is it x1,2 = -b+/- sqrt(D) / 2a. Please help me this is urgent -

so ax^2+bx+c=0 is standard form of a quadratic, its usually how they are presented to you
x = \frac{-b \pm \sqrt{b^2 -4ac}}{2a} is the general derivation for any given quadratic. if you plug in the vars for a,b,and c (referencing the standard form) and compute for both +/- (\pm in the formula) you will get a solution for each. (the D is the descriminant but i dont remember that that much so someone else can do the talking for me)
the reason why you have 2 solutions is that when you step through and compute the values of x (given a decent range of iteration) as long as the range is not greater than one, you will have either 1 or 2 solutions (ie when x=0) if its greater than 1 you get 1 or two imaginary solutions (ie not on the standard 2d plane)† top dog :pedomustdie: likes this. -

I was explaining the same thing just now lol -

ok for the discriminant, its really only useful for helping you determin if there are 1,2 or nonreal solutions for the given equation so given d = x^2 - 4ac (the descriminant) for your calculations come out to be a...
- positive number: there are 2 distinct real solutions
- zero: one (often repeated) real solution
- negative number: there are no real solutions (probably 1 or 2 nonreal)
