i was trying to do this program, but i find it difficult to solve it!!

could you please help me?

this is the question,

write a C program that can find the root of equation using bisection method. given that f(a) is 1st point, f(b) is 2nd point amd f(m) is middle point.

f(x)= x^2 + 5

prog should stop when f(a)-f(b) is less than 0.0000001. program should display root of equation (x, when f(a) or f(b) < 0.0000001), number of iteration used. user should be able to retry again or end the program..

pleasa help me... thanks
