Student Notes with work

Multiply 2 binomials by distributing:

(x+5) =

Examples: a) horizontal b) vertical

Multiplying BinomialsThe product of two polynomials is always a polynomial. So, like the set of integers, the set of polynomials is closed under multiplication. You can use the Distributive Property to multiply two binomials.

Example: two­way tablec) Find (2x ­ 3)(x + 5).

***Always combine like terms in your final answer.***
