It is easy to check that f(r) = x² - 4x has two roots. Find these two roots using Newton's method - f(rm)/f'(In). (11) In+1 = I, - If you can find only one root, explain why? [Hint: First write the Newton's iteration formula, then use different initial values 10=1 and then ro = -1 to see if you can get two different roots.]
