One of the problem in operation calculation of mathematics that is in course of calculation to determine roots from an equation of polinomial having degree n. solution of the problem difficult enough if finished by calculation of analytic method or habit. If analytic method cannot be applied, hence solving of from the problem is searched by using method of numeric. Method of numerik is an technique used for formulating problem of mathematics so that they earn to be solved with calcultion operation or of arithmetic, and in every its computing step entangle system of computer because its calculation operation quite a lot, complicated and repeatedly. To determine roots equation of polinomial degree of n or in this case having maximal degree five. Solution can use Method of Newton Raphson and Method of Secant. However, result of calculation from is both of method above is not absolute correctness, but can come near value in facy hacing mistake in every its calculation.
