Solve the problem.Use Newton's method to estimate the solutions of the equation 
. Start with 
for the right-hand solution and with x0 = -1.5 for the solution on the left. Then, in each case find x2.
What will be an ideal response?
f(x) = 
, f'(x) = 8x3 + 3
Right-hand solution:
x1 = 1
xn + 1 = xn - 
= 
therefore x2 = 0.9091
Left-hand solution:
x1 = -1.5
xn + 1 = xn - 
= 
therefore x2 = -1.4323
