I don't know why people like long methods, when you have short ones...lol...
Precal_Chris said:oh dang that's where i went wrong last time i put h as -1 ...-.-
im getting x and h confused...
so when h is taken out of the denominator i should have...
-3x(^2) -3xh -h(^2) +8x +4h
correct?
then placing 0's in for h should make it...
-3x(^2)- 3x(0)-(0)(^2) +8x + 4(0)...
leaving me with
-3x(^2)+8x...
right?

Precal_Chris said:who's OP?
yourdadonapogostick said:OP doesn't know the shortcut yet and was instructed to do this method.
Precal_Chris said:oh...lol
our teacher said there was a way easier way to do this but she wouldn't tell us...
sutupidmath said:Well, with shortcut here i meant to use the other alternative of the deff. of the derivative,
[tex]\lim_{x\rightarrow -1}\frac{f(x)-f(-1)}{x+1}[/tex] it takes you much faster to the answer.
Maybe not but you usually act like a smart ass, but it's all good we still love you and we all do at one point in time :psutupidmath said:"i don't know why people like long methods when there are short ones".

LOL, I was the same way last summer. Math is awesome :) If you can, take up to Calculus 3 and you'll be happy :)Precal_Chris said:wow and you guys knew how to do this all along...
thats crazy how do you guys know all of that?

yourdadonapogostick said:I'd prefer not to resort to synthetic division.
sutupidmath said:Well, you will learn this stuff, don't worry about that. I didn't know you were still in high school...lol...
