    I know you're supposed to multiply the last terms in the brackets together to get the y intercept, I was just wondering with the (2x-5) bracket, does it need simplifying to x = -2.5 first or can I just multiply the terms and leave the (2x-5) bracket as it is?

    To get the y intercept you need to make x=0 as that is where it crosses the y axis.
    And no 2x=0 so it's (0-5)(0-1)(0+2)

    Stay relax and don't make things hard.

    The main point is that x=0 at y-intercept.Substitute x=0 and you will get

    (2*0-5)(0-1)(0+2) = (0-5)(0-1)(0+2)
    = -5*-1*2
    = 10

    I know, I really hope I do well now, in the process of doing all the past papers a second time round to *hopefully* see that I've learnt from my past mistakes

    Have you done all the solomon press papers? I'm doing one a day and it seems to be workly very effectively, I've got 3 more real papers so by the time I get to the exam day I'll be done with them all.

    tbh, I take one look at the Solomon papers and they just freak me out! I think I need today to become more confident at C1 as my grade fluctuates a lot from a low B to an A & there's random questions I don't understand yet, so just kind of re-doing papers I got a B on and bringing them up to A's first. I think tomorrow I'll do a Solomon because pretty much everyone is recommending them. Good luck on C1, you seem very well prepared

    THIS is exactly what I needed! I was always worried about how I'd start a solomon paper, barely be able to do a question, no one would be able to make me understand and I'd lose all confidence in C1 but I usually understand videos from maths247.

    Thank you!
