Question

could you please help me with part c and d , please provide written out explanations 

2. Let A and B be arbitrary constants. For each of the following y(x), find a differential equation that y(x) satisfies, with the order of the ODE equal to the number of arbitrary constants in y(x). The ODE should not contain any arbitrary constants. (a) y(x) = cos x + Ax² (b) y(x) = sin(x + A) (c) y(x) = A cos x + B sin x + x² (d) y(x) = A(x² - 1) + Bx
