In particular, Quintic equations, homogeneous and non-homogeneous have aroused the interest of numerous mathematicians since antiquity (Dickson, 1; Mordell, 1). For illustration, one may refer (Gopalan and Vijayashankar, 010; Gopalan and Vijayashankar, 010; Gopalan et al., 01) for Quintic equation with three unknowns and (Gopalan and Vijayashankar, 011; Gopalan and Vijayashankar, Gopalan et al., 01; Gopalan et al., 01; Gopalan et al., 01; Vidhyalakshmi et al., 01; Vidhyalakshmi et al., 01) for Quintic equation with five unknowns. This paper concerns with the prolem of the non-homogeneous Quintic equation with five unknowns given y x y (x y )(x y) (z w )p. A few relations among the solutions are presented. Method of Analysis The non-homogeneous quintic equation with unknowns to e solved is given y x y (x y )(x y) (z w )p (1) Assume x u v, y u v, z u v and w u v () Sustituting () in (1), it leads to

Write 1 as 1 ( i )( i ) () Using () & () in () and employing the method of factorization, define u i v ( i )(a i () Equating the real and imaginary parts of (), we get u a a a (7) v a a a (8) Sustituting (7) and (8) in (), the integral solutions of (1) are given y x a a 0a 0 () y(a, y a a 0a 0 (10) z 7a 1a 0a (11) w a a 7a (1) along with () Properties y(1, n) w(1, n) z(1, n) OHn SO n 8Pn 8t, n 0(mod ) x(1, n) y(1, n) z(1, n) w(1, n) 7RDn Pn 00t, n (mod 8) x(n,1) RDn 11(mod ) y(a, 0 y (a, z (a, 7w (a, y(a, 0 Note 1 In (), the representations of z and w may e taken as z uv, w uv (1) In this case, the values of z and w are given y z a a 0a 00a 0a 00a 70 (1) w a a 0a 00a 0a 00a 70 (1) Thus (), (10), (1), (1) and () represent a different set of solutions to (1) Note Oserve that z and w in () may also e taken as z uv, w uv (1) For this choice, the corresponding values of z and w are otained as Copyright 01 Centre for Info Bio Technology (CIBTech) z a a a 00a 1a 00a 7 (17) w a a a 00a 1a 00a 7 (18)

CONCLUSION In this paper, we have illustrated different methods of otaining non-zero integer solutions to the Quintic equation with unknowns given y x y (x y )(x y) (z w )p. As the Quintic Diophantine equation are rich in variety one may consider other forms of Quintic equation with variale and search for their corresponding integer solutions along with the corresponding properties.
