MathBot Answer:

Evaluated



\(\displaystyle \left(x - 0.4\right) \cdot \left(x - 0.5\right) \cdot \left(x - 0.7\right) = \left(x - \frac{7}{10}\right) \left(x - \frac{1}{2}\right) \left(x - \frac{2}{5}\right) \)

Expanded

\[\left(x - 0.4\right) \cdot \left(x - 0.5\right) \cdot \left(x - 0.7\right) = x^{3} - \frac{8 x^{2}}{5} + \frac{83 x}{100} - \frac{7}{50}\]

Factored

\[\left(x - 0.4\right) \cdot \left(x - 0.5\right) \cdot \left(x - 0.7\right) = \frac{\left(2 x - 1\right) \left(5 x - 2\right) \left(10 x - 7\right)}{100}\]
