# Differentia

Answer :

Let, y = We have to find dy/dx

As we can observe that y is a fraction of two functions say u and v where,

u = x2 – x + 1 and v = x2 + x + 1

y = u/v

As we know that to find the derivative of fraction of two function we apply quotient rule of differentiation.

By quotient rule, we have – …equation 1

As, u = x2 – x + 1 …equation 2 { }

As, v = x2 + x + 1 …equation 3 { }

from equation 1, we can find dy/dx  {using equation 2 and 3}  Hence, Rate this question :
