A simple and e±cient method is proposed for approximation of the solu-
tion of Fredholm integral equation. The method is based on polynomial expansion of
given data using polynomial ¯tting. First kind integral equation of convolution type,
can be reduced to a linear upper triangular system which can be directly solved by
backward substitution. The method applied to two test problems, computed solutions
are compared with exact solutions to show the e±ciency of proposed method.
