Question

y=x+2/(x^2+4) differentiation​

Answer 1

y=

x2-4

x2-2x

Differentiate using the Quotient Rule which states that

d

dx

[

f(x)

g(x)

] is

g(x)

d

dx

[f(x)]-f(x)

d

dx

[g(x)]

g(x)2

where f(x)=x2-4 and g(x)=x2-2x.

(x2-2x)

d

dx

[x2-4]-(x2-4)

d

dx

[x2-2x]

(x2-2x)2

Answer 2

I am a student of 8th class i dont know much but if

X^n=nX^n-1 so

derivation of a constant is zero

d/dx = 1+0÷ 2+0

d/dx=1/2
