Euler's method - Oira no Kaihou

...For this equation, T 3pT 2 -4 rT +(4 prq 2 )=0 ...If you take one of the roots t of (2), the roots of (1) can be obtained as the roots of the following two quadratic equations (Ferrari's solution). Also, if the three roots of are u 2 , v 2 , and w 2 , the roots of (1) are u + v + w , u - v - w , - u + v - w , and - u - v - w (Euler's solution). (e) There are no formulas like (b) and (d) for the fifth degree or higher. ...

*Some of the terminology that refers to "Euler's solution" is listed below.
