Class 12 Mathematics - Chapter Differential Equations NCERT Solutions | y = x2 + 2x + C : y'&

Welcome to the NCERT Solutions for Class 12th Mathematics - Chapter Differential Equations. This page offers a step-by-step solution to the specific question from Exercise 2, Question 2: y x2 nbsp 2x c nbsp nbsp y 39 nbsp 2x....
Question 2

y = x2 + 2x + C y' - 2x - 2 = 0   

Answer

y = x2 + 2x + C

Differentiating both sides of this equation with respect to x, we get:

\begin{align}y^{'}=\frac{d}{dx}(x^2 + 2x + C)\end{align}

=> y' = 2x + 2

Substituting the value of y' in the given differential equation, we get:

L.H.S. = y' - 2x - 2 = 2x + 2 - 2x - 2 = 0 = R.H.S.

Hence, the given function is the solution of the corresponding differential equation.
