I. 14p2 – 135p + 81 = 0
II. 7q2 – 65q + 18 = 0
ATQ, From I: 14p2 – 135p + 81 = 0 Or, 14p2 – 126p – 9p + 81 = 0 Or, 14p(p – 9) – 9(p – 9) = 0 Or, (14p – 9)(p – 9) = 0 Or, p = (9/14) or 9 From II: 7q2 – 65q + 18 = 0 Or, 7q2 – 63q – 2q + 18 = 0 Or, 7q(q – 9) – 2(q – 9) = 0 Or, (7q – 2)(q – 9) = 0 Or q = (2/7) or 9 So, no relation can be established between ‘p’ and ‘q’
