(subtracting polynomials)...Aliens... HEAR MY WISDOM!!

Earthlings: Subtracting polynomials is the same as Adding polynomials except we have to change the subtraction sign into an addition sign.
Aliens: How do you solve this "Wise One"?...... (5x + 10y + 11) - (10x + 15y + 13)
Earthlings: Like this..

Step one:
Write terms in column form with their like terms

(+5x +10y +11)
- ( +10x +15y +13)

Step two:
Change the second set of polynomials to the opposite sign and change the subtraction sign to an addition sign, this is called the additive inverse.

(+5x +10y +11)
+ (-10x -15y -13 )

Step three:
Add all the like terms together.

(+5x +10y +11)
+ (-10x -15y -13 )
-5x -5y -2

Aliens: thank you kind earthling.... maybe now we'll jus bother ms. armstrong more..... for we crave this..... wisdom....

Awesome job Arvin,
Accurate and funny...what more could the aliens want??? Oh ya, they wanted to know your measurements for the new crown and robe they are designing for you...I think they have you going back with them on the mother ship.
