+ Encuentra las raíces de la ecuación x ^ 3-21x + 20 = 0
+
+Commands:
+=========
+eq1: x^3 -21*x+20=0;
+
+solve(eq1,x);
+
+Solution:
+=========
+(%i1) eq1: x^3 -21*x+20=0;
+                               3
+(%o1)                         x  - 21 x + 20 = 0
+(%i2) solve(eq1,x);
+(%o2)                       [x = 1, x = 4, x = - 5]
