# Thread: How do I find the values of....

1. ## 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,

$\displaystyle -2=(-3)^2+p(-3)+q$

$\displaystyle 3=2^2+2p+q$

Hope you can continue.

3. Awsome! Thanks very much, carried on from there and got the right answers! Thank you very much!
