## Roots Of f(x)= 0,1x³ - 0,9x

The function term is: f(x)= 0,1x³ - 0,9x What are the roots of it? Change the term: f(x) = x (0,1x² - 0,9) For x1 = 0 the term becomes Zero. 0,1x² - 0,9 = 0 is 0,1x² = 0,9 is x² = 9 This is true for x2 = 3 and x3 = -3. So the 3 solutions to this term are x1 = 0 x2 = -3 x3...
