11-14.
  1. Multiple Choice: Which of the following expressions is the product of (4y − 3x)(2y + x)? Homework Help ✎

    1. 8y2 − 2xy − 3x2

    2. 6y2 − 2xy − 2x2

    3. 8y2 + 10xy − 3x2

    4. 6y2 − 2x

Use a generic rectangle to multiply the expression together.

Multiply each row by each column. Add the products together to get the final product.

(4y − 3x)(2y + x) = 8y² − 2xy − 3x²
