SUMMARY
The discussion focuses on finding the values of p and q in the polynomial equation px^3 + qx^2 - 3x - 7, given that (x-1) and (x+1) are factors. To solve for p and q, one must apply the Factor Theorem, which states that if (x-1) and (x+1) are factors, then f(1) = 0 and f(-1) = 0. By substituting these values into the polynomial and forming simultaneous equations, the values of p and q can be determined definitively.
