1. POLYNOMIALS – Sum and Difference
The addition / subtraction of polynomials is exactly like binomials. You just have more than two terms in the parentheses. If a subtraction sign appears in front of a set of parentheses, make your changes then add.

10. POLYNOMIALS – Sum and Difference
There is another method to attack these problems. You must decide which method is best for you.
EXAMPLE # 1 :
Looking at this first polynomial, there is nothing to the left of the polynomial that changes what is inside.
So we will DROP the parens and write down EXACTLY what we see.

12. POLYNOMIALS – Sum and Difference
There is another method to attack these problems. You must decide which method is best for you.
EXAMPLE # 1 :
Looking at the 2nd polynomial, there is a negative to the left of the polynomial that changes what is inside.
So we will DROP the parens and write down our changed signs…
