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

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

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

(x +2)(x + 3)

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

(x + 5)(x + 4)

• x² + x + 20
• x² + 20x + 9
• x² + 9x + 20
• x² - 9x + 54

(x + 7)(x + 9)

• x^2 + 63x + 16
• x^2 + 16x + 63
• x^2 + 79
• x^2 + 16x + 2

(x + 5)² 

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

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

(x + 7)(x - 2)

• x^2 - 5x + 5
• x^2 - 9x - 14
• x^2 - 5x - 14
• x^2 + 5x - 14

(x - 3)(x +10)

• x² - 7x + 13
• x² - 6x - 30
• x² + 7x - 30
• x² + 13x + 30
