    Right okay, I'm stuck!

    Quadratic equation.... (2k-3)x^2+2x+(k-1)=0
    K is a constant, has real roots

    show that 2k^2-5K+2 is less than or equal to 0

    i've done this but ..???

    b^2 - 4ac is greater than or equal to 0

    2^2 - 4 x (2K - 3)(k-1) is greater than or equal to 0

    4 - 4(2k^2 - 5k + 3) is greater than or equal to 0

    I end up with

    2k^2 - 5k + 3

    where am i going wrong?

    4 - 4 ( 2k^2 - 5k + 3 ) does not equal 2k^2 - 5k +3

    You need to multiply the brackets out by the -4 instead

    Yeah, you expand 4-4(2k^2 -5k +3)
    to get 4 - 8k^2 +20k -12 > 0
    which simplifies to -8k^2 +20k - 8 > 0
    and if you flip it all to the other side of the equation
    8k^2 -20k + 8 < 0
    divide by 4
    2k^2 -5k + 2 < 0
