Multiplying and Adding Negative Numbers

The video tutorial explains how to multiply a trinomial by constants, including a negative constant. It begins with distributing the constants across the trinomial and then combines like terms to simplify the expression. The process involves careful attention to signs, especially when dealing with negative numbers, and concludes with a simplified expression.

What is the first step in multiplying a trinomial by a constant?

• Add the constant to each term

• Subtract the constant from each term

• Divide each term by the constant

• Distribute the constant to each term
