Adding and Subtracting Polynomials
You have used properties to simplify expressions.
4a + 3a - 2 = (4 + 3)a - 2 Distributive Property
= 7a - 2 Substitution Property of Equality
5x2 + 3y + 2x2 - y= 5x2 + 2x2 + 3y - y Commutative Property of Addition
= (5 + 2) x2 + (3 - 1)y Distributive Property
= 7x2 + 2y Substitution Property of Equality
Suppose you want to add the polynomials (3x + 2y) and (8x + 3y).
You can use the same properties to find the sums.
