Drama: Macbeth

Poetry: My Last Duchess or Valentine

I've also got The Great Gatsby which I'll do if my back's really to the wall and I've got a rescue text, The Telegram as a last ditch attempt. Also got a few more poems by Carol Anne Duffy. Hoping I'll be able to fit something together and pick up a lot of the marks in the close reading.

I've cut all the usual rubbish about the context of the question out to make it easier to type.

**Curve PQ has equation . The line PQ is horizontal.**

The -coordinates of P and Q are -1 and

(a) Show clearly that the equation of the line PQ is =4 (Done this part OK)

(b) Hence determine the value of

The -coordinates of P and Q are -1 and

*a*respectively.(a) Show clearly that the equation of the line PQ is =4 (Done this part OK)

(b) Hence determine the value of

*a*It is part b I am having problems with, I thought that using part (a) I could substitute

*a*in to get the polynomial and then go through the process to solve it and get the second root which would be

*a*. I can't get this to work however and therefore I' hoping someone will help me with this.

There is a graph which I've done roughly below. Apologies for the bad drawing.

Thanks!!
