# Lesson 44: Polynomial Operations (Addition/Subtraction and Multiplication)

Lesson on simplifying polynomial based on the mathematical operation given. Adding and subtracting polynomial expressions are done by combining like terms. Multiplying polynomials are done by applying the distributive property and following the laws of exponents.

0:16 (2x + 3y + 7) + (3x -- y -- 5 )

1:26 (5x -- 3y + 5) -- (2x + 5y - 5)

3:29 5(2x + 3y) 3:49 2x^2 (3x^5 + 7)
