I. 25p + 2(2p2 – 1) = 8(p + 5)
II. 8q2 + 35q – 78 = 0
ATQ, 25p + 2(2p2 – 1) = 8(p + 5) Or, 25p + 4p2 – 2 = 8p + 40 Or, 4p2 + 17p – 42 = 0 Or, 4p2 + 24p – 7p – 42 = 0 Or, 4p(p + 6) – 7(p + 6) = 0 Or, (4p – 7)(p + 6) = 0 Or, p = (7/4) or -6 From II: 8q2 + 35q – 78 = 0 Or, 8q2 + 48q – 13q – 78 = 0 Or, 8q(q + 6) – 13(q + 6) = 0 Or, (8q – 13)(q + 6) = 0 Or, q = (13/8) or -6 So, no relation can be established between ‘p’ and ‘q’.
