v Du - u Dv
use the formula D(u/v)= ----------------
                                                        v^2

yeah i did lol but i think i stuffed something up, can you please solve it for me

anonymous · Answer

let u=x^2, u= x-1, 
then
(x-1)2x - x^2
-----------------
    (x-1)^2                             can you continue that pls...

@sirm3d, do you have something to help yasmin plzz?
you can go ahead and reply ... :D

$$\large v=x-1\\large Dv = 1 - 0 = 1\\large u=x^2\\large Du=2x$$ just sub the expressions u, Du, v, and Dv in $$\large D\left(\frac{u}{v}\right)=\frac{v Du - u Dv}{v^2}$$ as given by @mark_o.
