Multiplying Binomials

The length of a rectangle is x + 2 units and the width is 3x + 7
 units. Find the area.

• 3x² + 9x + 14 square units
• 3x² + 13x + 14 square units
• 4x + 9 square units
• 8x + 18 square units

Write the expanded (general) form of the product (x+3)(x+6).

• x²+18x+9

• x²+9x+18

• x²+18x+18

 Multiply:
(r + 7)(r − 7) 

• r ² − 49 
• r ² + 14
• r ² − 7r + 49 

Find the product:
(y - 3)(y + 7)

• y² - 21
• y² + 10x - 21
• y² + 4y - 21
• 2y - 10

Find the product:
