    How do I find the values of....

    Im really stuck on this question i have in my core 1 maths book. Ive searched throughout the chapter on how to do it but cannot find an answer.
    The question is;

    The curve C with equation y = x^2 + px + q, where p and q are intergers, passes through A and B coordinates. Find the values of p and q

    A(-3,-2) B(2,3)

    I have no idea where to start. Help will greatly apprietated.

    Dear StevieGwonder,

    Since the curve passes through the two points A and B, the equation must satisfy those points. That is,

    -2=(-3)^2+p(-3)+q

    3=2^2+2p+q

    Hope you can continue.
