3 2 x + 3*x + 3*x + 2 ------------------- 2 x + 2*x + 1
(x^3 + 3*x^2 + 3*x + 2)/(x^2 + 2*x + 1)
Apply the quotient rule, which is:
and .
To find :
Differentiate term by term:
The derivative of the constant is zero.
Apply the power rule: goes to
The derivative of a constant times a function is the constant times the derivative of the function.
Apply the power rule: goes to
So, the result is:
The derivative of a constant times a function is the constant times the derivative of the function.
Apply the power rule: goes to
So, the result is:
The result is:
