    Hi i have been doing inequalities on integral maths and im really stuck on a few questions can you help?

    1) The solution to the inequality
    2x2x3>0
    is written in the form
    x < p or x > q
    p < x < q

    with p = Answer

    and q = Answer
    .


    2) The solution to the inequality
    8+2xx2<0
    is written in the form
    x < p or x > q
    p < x < q

    with p = Answer

    and q =

    3)The solution to the inequality6x2+x20
    is written in the form
    xp or xq
    pxq

    with p = Answer and q = Answer.
    (Give answers as exact whole numbers or decimals, or as fractions in the form a/b).

    4)The solution to the inequality

    2x2x+1>x24x1
    is written in the form
    x < p or x > q
    p < x < q

    with p = Answer and q = Answer.
    (Enter your answers as exact integers or decimals, or as fractions in the form a/b).



    5)The quadratic equation
    x2+(k1)x+4=0
    has at least one real root.
    The range of possible values of k is written in the form
    x < p or x > q
    p < x < q
    xp or xq
    pxq

    with p = Answer and q = Answer.
    (Enter your answers as exact integers or decimals, or as fractions in the form a/b).

    6)The solution to the inequality

    x25x+4>0
    is written in the form
    x < p or x > q
    p < x < q

    Mark 1.00 out of 1.00

    with p = Answer

    and q = Answer
    .(Enter your answers as exact integers or decimals, or as fractions in the form a/b).

    Can you help me please, i really dont understand what it's asking me. Would be great if someone could offer answers or step by step answers. Thanks in advance.

    I'd suggest just concentrating on one of these at a time until you get the hang of it!

    For Q1, can you factorize the quadratic? Can you see from that which values of x satisfy the inequality? Are the range of values contained in some interval like p < x < q, or are there 2 distinct ranges of values like x < p and x > q?

    To add to davros, it might be illuminating for you to draw a little sketch of the quadratic in each case, labelling certain key points.
