# AQA FP3 Differential equation - must be obvious but not to me watch

1. I'm trying, for the umpteenth time, Q2 on page 130 of the AQA FP3 booklet.

In the PDF below I am posting both the question and my answer. I have left this question and moved on but have now come back to it and I'm still doing it the same way as I was the first time. I have followed an example of page 110 of the book and just can't see where my mistake is.

You have the correct solution. y(x)=0.

You could try it with y(0)=1 and y'(0)=1 and check your answer here.

Good and thanks. Very useful tool, I will try to remember to use it when I get really stuck again.
