Question
Form the differential equation from the following primitives where constants are arbitrart:$\text{y}=\text{ax}^2+\text{bx}+\text{c}$

Answer

The equation of family of curves is
$\text{y}=\text{ax}^2+\text{bx}+\text{c}\ ...(1)$
where a, b and c is an arbitrary constant. so, we shall get a differential equation of third order.
Differentiating equation (1) with respect to x, we get
$\frac{\text{dy}}{\text{dx}}=2\text{ax}+\text{b}\ ...(2)$
Differentiating equation (2) with respect to x, we get
$\frac{\text{d}^2\text{y}}{\text{dx}}=2\text{a}\ ...(3)$
Differentiating equation (3) with respect to x, we get
$\frac{\text{d}^3\text{y}}{\text{dx}3}=0$
It is the required differential equation.
