A1 8.3 Practice

Find the product:
(3x + 2)(2x + 4)

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

(x +2)(x + 3)

• x² + 5x + 6
• x² + x + 6
• x² + 5x + 5
• x² + 6x + 6

(x + 5)² 

Hint: try (x + 5)(x + 5)

• x² + 25
• x² + 10x + 25
• x² + 10 x + 10
• x² + 10

Find the Product.

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

• 4n² + 8n + 3

• 4n² - 8n - 3

• 4n² + 8n - 3

• 4n² - 8n + 3

Simplify
(p − 8)²

 Hint: (p − 8)² = (p − 8)(p − 8)

• p ² − 16p − 64 
• p ² + 16p + 64 
• p ² − 16p − 8
• p ² − 16p + 64 

Find the product:
(3x – 1)(x + 5) 

• 3x² + 4x + 5
• 3x² + 4x - 5
• 3x² + 14x + 5
• 3x² + 14x - 5

Find the product:
(x + 12)(x - 12)

• x² - 144
• x² + 144
• x² + 12x - 144
• x² - 12x + 144

Simplify the following expression:  
(-x - 3)(x + 5)

• -x² + 2x - 15
• -x² - 8x - 15
• x² + 2x - 15
• -x² - 8x + 15

Simplify the following expression:
(4x - 1)(4x + 1)

• 16x² + 8x - 1
• 8x² + 8x
• 8x² - 1
• 16x² - 1

Distribute and combine like terms. 
(-x - 1)(x - 11)

• -x² - 12x - 12
• -x² - 12x + 11
• -x² + 10x + 11
• -x² + 10x - 12
