Writing Project 36:

Tartaglia, Cardano, and the cubic and quartic formulas

When were the formulas for solving cubic and quartic equations (finding zeros of polynomials of degree 3 and 4) invented? Who deserves the credit for them? Describe the interesting stories behind these formulas. Also describe these formulas, and how they are used to get solutions.
