Question

find dy/dx. do not simplify with exception of multiplication of numbers

y=(x+1)(x^2+1)

Step 1

**Product rule of differentiation:**

If *f*(*x*) is a function of *u *and *v *where both *u *and *v *are variables then the derivative of the function *f*(*x*) is obtained by the formula given below:

Step 2

**Find the derivative ( dy/dx):**

The given function is *y *= (*x* + 1)(*x*2+1).

The derivative of *y *is obtained as **3 x2 + 2x +1** from t...
