A) Show that the equation x3 + 6x - 5 = 0 has a solution between x = 0 and x = 1 b) Show that the equation x3 + 6x – 5 = 0 can be arranged to give x =
5
X2 + 6
by filling in the boxes. x3 + 6x -5 = 0
x3 + 6x =
X =
(x2 + 6) =
5
x2 + 6
c) Starting with x = 0, use the iteration formula xt1 =
5
X,2 + 6
twice,
to find an estimate for the solution of x3 + 6x - 5 = 0
