I get your problem, but the answer is it should be divided by both, because actually, it's dividing both. For eg (1+3)/2 is the same as 1/2 + 3/2 = 0.5+1.5 = 2. And not 1/2 + 3 or 1 + 2/3.
@@SkanCityAcademy_SirJohn Never mind. I got it 👍🏾. I’ve realised that’s how it’s done when it’s addition. I was confusing it with multiplication. It’s been long since I’ve done mathematics so I’m a bit rusty 😂
@@SkanCityAcademy_SirJohn It was example 3. When you were substituting the y¹ and y expressions into the differential equation you considered the second term as y/(X+1) instead of 2y/(X+1). Correct me if I'm wrong
You see, from the question you can see the expression for 2y, and that is the substitution I've made. And that is correct. Maybe you want me to multiply it this way, 2y = 2(1/2(x+1)^4 + c/2(x+1)^2). That is another way but it's going to look scary.
