Do you still get the marks if you use the quadratic equation to factorise the last one and leave it in quadratic formula form?

What question was this?
Anyone get the first question (surds) as a fraction
Anybody got 3root 5 for the length of the chord?

No, you have to find the crit. values from using the quadratic formula (if you used this method) and sketch a graph, then state the possible values using inequalities. I think you'll maybe get 1/2 marks.

Last year's was harder imo, I predict ~59 for an A.


I thought last year’s was harder as well. I was shocked at the amount of people who thought this paper was atrocious when I left the exam hall.

Probably because of all the fractions...
someone explain the area of shaded triangle?
and also for the gradient of normal it was just the gradient of c and p not the reciprocal?

Did you do this for the K question finding the discriminat? Because I left it in quadratic format something like (42+/- root 1298) /20 but I think we’ll loose a mark for not putting it in its simplest form
