Doing this quadratic s--- and the quadratic formula. As an example, can someone do
6x^2 - 2x + 3 = 0
this way:
Find the discriminant
Plug the discriminant into the b^2-4ac part of the Quadratic Equation
Put into simplest radical terms
the little carrot thingy like this 6x^2 means it is to the second power in case of some you dont know
;_; please help -
But I'm too lazy to.
-
cries
-
Plus even if I know I'm right, I'm afraid people will judge my answer. Okay, I'm sorry for wasting your time. o.o
-
okay ;_:

Wait.
All you're doing is plugging in numbers into an equation. It's fun. 83 -
YES but i dont know how to simplify it
-
a = 6
b = -2
c = 3
The discriminant is just b squared minus 4 times a times c.
Then when you plug a b and c into the quadratic equation, the b squared minus 4 times a times c part is already done.
x = -b plus or minus the square root of b squared - 4 times a times c over 2 times a
Oh mah gawd this is so much fun. I'm gonna marry the quadratic formula. -
I'm probably not helping. :P
Sorry. I actually know now to do this, but I don't have anything to write it out on. -
i know how to do up to that
but i have to simplify the radical
how do that -
like how do simplify something like 54 under a radical just to go off of that
-
I love simplifying radicals. OuO
But I suck at teaching. Basically you think of two numbers that multuply together to get the number in the radical as the product, but one of those two numbers needs to be a perfect square.
So if I simply the square root of 27, it would be plus or minus 3 root 3 since 9 times 3 equals 27 and 9 is a perfect square. -
Ooooo 54 would be 3 root 6
because 9 times 6 equals 54 and 9 is a perfect square :D -
okay so
let's say 48
6 * 8 = 48
2 * 3 = 6 2 * 4 = 8
is it 2 root 12 like that's what i dont get
what gets the rooty numbers -
f--- THATS WRONG I THINK
it has 16 x 3
4 root 3 bc 16 is perfect square
so is it best to try and find perfect square factors
