Question 173003
Multiply out: 
(x +6)(x^3 - x^2 - 5x +1) 
x.x^3 - x.x^2 - x.5x +x.1 + 6.x^3 - 6.x^2 - 30x +6.1 = 
x^4 - x^3 - 5x^2 + x + 6x^3 - 6x^2 - 30x  + 6 =
x^4 + 5x^3 - 11x^2 - 29x + 6
===============================
The rule is "every term of x^3 - x^2 -5x +1 must be multiplied
by each term of x + 6
================================
