I do just want to ask why you want it inline, because if it is such a big equation and it is in the middle of a paragraph, then it will wreak havoc with the spacing of the text lines around it? Or do you want it inline in order to add an equation number?
If you want it inline in the paragraph, then firstly, turn non=printing characters on (Ctrl+Shift+8, or, in other words, Ctrl+*). You will notice that at the right of the equation, a paragraph end mark is added (the pilcrow symbol you should now see). delete this, and it will be inline, but still in the so-called display format.
If you just want to add a number, see what I have written here:
