Exam 5 (CH1-5) Review (22/23)

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

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

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 

Factor x² + 7x + 12

• (x + 2)(x + 10)
• (x + 3)(x + 4)
• (x + 4)(x + 5)
• (x + 4)(x + 6)

Factor:
 4x²-16x-9

• (2x-9)(2x+1)
• (2x+9)(2x-1)
• (4x-1)(x+9)
• (x+1)(4x-9)

Factor completely: 3x² - 7x + 2

• (x - 1) (3x + 2)
• (x - 2) (3x -1)
• (x - 1) (3x - 2)
• (x + 2) (3x + 1)

Factor 9c² - 100.

• (c - 10)(c + 10)

• (3c - 10)(3c + 10)

• (9c + 100)(9c - 100)

• (9c - 10)(9c + 10)

What is the line of symmetry for the parabola?

• x = -2

• x = 2

• y= -2

• y = 2

Write an equation for the graph.

• y = -(x+6)(x+1)

• y = (x-6)(x+1)

• y = (x+6)(x+0.5)

• y = - (x + 6)(x + 0.5)

Write an equation for the table.

• y = (x-4)(x+1)

• y = (x+4)(x+1)

• y = (x+4)(x-1)

• y = - (x+4)(x-1)

12. Solve using any method.

(x - 2 )² -49 = 0

• 5, 9

• ^{-9, -5}

• 9, -5

• ^{9, -9}
