Question

1. Form the differential equation of which each of the following function
is the primitive. State the order and degree of the equation; ak
say whether the equation is linear or not, (A, B, C, D are arbitrar
constants :
(a) y = Ax2 + Bx;​

Answer 1

Primitive is integral
y=Ax^2+Bx is integral of a function say f(x)
So f(x) is its derivative
f(x)=dy/dx
f(x)=2Ax+B
It is a linear equation(or function)

Thank me if understood
