Question 1038324
*[invoke explain_simplification "x+x-x+2x=6" ]You can multiply polynomials horizontally or vertically.
Examples
Horizontal:
(x+3)(x+2):
= (x+3)(x)+(x+3)(2)
= x(x)+3(x)+x(2)+3(2)
= x2+3x+2x+6
= x2+5x+6

Vertical - same equation:
  (x+3)(x+2):
     x+3
    ×x+2
    ----
    2x+6
x^2+3x
------
x^2+5x+6 notice that I get the same answer as before.
