Answer:

u = -2/3

Step-by-step explanation:

-3 = -1/ (u+1)

Multiply each side by (u+1)

-3 *(u+1) = -1/ (u+1) * (u+1)

-3 (u+1) = -1

Distribute

-3u -3 = -1

Add 3 to each side

-3u -3+3 = -1+3

-3u = 2

Divide each side by -3

-3u/-3 = 2/-3

u = -2/3

Answer:

-2/3

Step-by-step explanation:

multiply each side by u +1 to get it out of the denominator

-3(u + 1) = -1

now use distributive property

-3u - 3 = -1

add the 3 to move it over

-3u = 2

now divide by -3

u = -2/3

Differentiate the following functions (x^3+1)(x-2)÷x^2

Masja [62]

Given:

The given function is:

$\dfrac{(x^3+1)(x-2)}{x^2}$

To find:

The differentiation of the given function.

Solution:

Consider the given function,

$y=\dfrac{(x^3+1)(x-2)}{x^2}$

It can be written as:

$y=\dfrac{(x^3)(x)+(x^3)(-2)+(1)(x)+(1)(-2)}{x^2}$

$y=\dfrac{x^4-2x^3+x-2}{x^2}$

$y=\dfrac{x^4}{x^2}-\dfrac{2x^3}{x^2}+\dfrac{x}{x^2}-\dfrac{2}{x^2}$

$y=x^2-2x+\dfrac{1}{x}-\dfrac{2}{x^2}$

Differentiate with respect to x.

$y'=\dfrac{d}{dx}(x^2)-\dfrac{d}{dx}(2x)+\dfrac{d}{dx}(x^{-1})-\dfrac{d}{dx}\2(x^{-2})$

$y'=2x-2(1)+(-x^{-2})-2(-2x^{-3})$

$y'=2x-2-\dfrac{1}{x^2}+\dfrac{4}{x^3}$

Therefore, the differentiation of the given function is $2x-2-\dfrac{1}{x^2}+\dfrac{4}{x^3}$ .
