Hi
1. Fist of all, use Wiris to correct the equations from yesterday.
2. Go to this page, read the theory and solve the questions. Use your notebook to do the calculations (ruffini, etc) and Wiris to check the answers.
3. Solve these equations and send me the answers in a word document:
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
