Jared Scribe post 6.2 adding and subtracting polynomials

A polynomial is a term or finite sum of the terms in which all variables have a whole number exponents and no variables appear in denominators or under radicals.
Here are more examples of polynomials: 3x-5, 4m^3-5m^2p+8, and -5t^2s^3.  REMEMBER, all monomials, binomials, and trinomials are polynomials.
To subtract two polynomials, add the first polynomial and the negative of the second polynomial.  

(-6m^2 -8m + 5) - (-5m^2 + 7m -8), change every sign in the second polynomial to add -6m^2 -8m +5 +5m^2 -7m + 8= -6m^2=5m^2-8m-7m+5+8 = -m^2-15 is the answer!!

To add polynomials combine like terms

(3a^5 - 9a^3 + 4a^2) + (-8^5 + 8a^3 + 2)
3a^5 - 8a^5 - 9a^3 + 8a^3 + 4a^2 + 2 = -5a^2 - a^3 + 4a^2 + 2
