Question

lim[Δx:0] ((2(x+Δx)^2+5Δx-2x^2)/(1(Δx))) find the limit plz help!

Answer 1

\[\lim_{x\rightarrow0} \frac{(2(x+\delta x)^2}{1(\delta x)}\]

Is this what you have been asked to find?

Answer 2

no

Answer 3

{lim x-0] 2(x+deltax)2+5x^2-2x^2 all over delta x

Answer 4

If so, I would rewrite it like this: \[\lim_{x\rightarrow0} \frac{2(x+h)^2}{h}\]

Answer 5

\[\lim_{x\rightarrow0}\frac{2(x+h)^2+5x^2-2x^2}{h}\]

Answer 6

limit is Δx

Answer 7

not just x-0

Answer 8

foil:
2(x+deltax)^2

Answer 9

= 2x^2 ...+

Answer 10

... 4*x*delta x +...

Answer 11

big finish... what's the last term in the expansion?

Answer 12
