0. First of all, use Wolframalpha (or Geogebra) to correct the homework from last days.
1. Start with this web page about ruffini.
2. Here you have some exercises. Solve them in your notebook using ruffini’s rule and check the solutions.
3. Solve these equations in your notebook. Use Wolframalpha (or Geogebra)to check the solutions.
2x4 + x3 − 8x2 − x + 6 = 0
2x3 − 7x2 + 8x − 3 = 0
x3 − x2 − 4 = 0
6x3 + 7x2 − 9x + 2 = 0
x3 + 3x2 − 4x − 12 = 0
4. This is a simple video about using ruffini’s rule to solve equations:
