Multiplying Binomials Lesson

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:
(3x + 2)(2x + 4)

• 6x² + 16x + 8
• 5x² +11x + 6
• 5x² + 16x + 6
• 6x² + 11x + 8

Find the Product.
(2x + 3)(2x - 3)

• 4x² - 9 
• 4x² + 9
• 4x²- 12x - 9
• 4x² + 12x - 9

Find the Product.

(2n + 3)(2n + 1)

• 4n² + 8n + 3

• 4n² - 8n - 3

• 4n² + 8n - 3

• 4n² - 8n + 3

(x + 5)²

• x² + 25

• x² + 10x + 25

• x² + 10 x + 10

• x² + 10

Which of the following is a binomial?

• 5x + 11
• x² + 3x + 6
• 12x²y
• x² - 4x + 10

Which of the following is a trinomial?
(If binomial is two terms, then trinomial is three terms.)

• x² + 7x + 12
• x + 8
• 9x - 5
• 15xy²
