• Factor x²y³ + xy

I can factor an "x" and a "y" out of each term: x²y³ = xy(x¹y²) = xy(xy²) and xy= xy(1).

   x²y³ + xy = xy(           )

   = xy(xy²        )

   = xy(xy² + 1)

Remember: When "nothing" is left after factoring, a "1" is left behind in the parentheses.

• Factor 3x³ + 6x² – 15x.

I can factor a "3" and an "x" out of each term: 3x³ = 3x(x²), 6x² = 3x(2x), and 
–15x = 3x(–5). Being careful of my signs, I get:

3x³ + 6x² – 15x = 3x(                    )

= 3x(x²               )

= 3x(x² + 2x      )

= 3x(x² + 2x – 5)

If I could go back to the year the watch was released 1971 and link I found a link way to acquire one I know I'd have a hell of a good time with it. Of course I'd have link to compete with King Hussein of Jordan legend has it that he took delivery of a large percentage of the 200 gold flightmasters produced.
