Question
I. p2 – 15p + 56 = 0 II.
q2 + 2q – 63 = 0 In the question, two equations I and II are given. You have to solve both the equations to establish the correct relation between p and q and choose the correct option.Solution
ATQ,
Solve p2−15p+56=0: Roots are p=7 and p=8. Solve q2+2q - 63 = 0: Roots are q = −9 and q = 7. Compare all cases: If p = 7, p≥q. If p = 8, p>q. Conclusion: p ≥ q
