Algebra 1 Ch 8 Test Review

Factor the Trinomial:
x² - 8x + 15

• (x + 5) ( x + 3)
• (x - 5) (x - 3)
• (x + 15) (x - 1)
• (x - 7) (x - 8)

Factor completely 
2c² + 4c - 84

• (c-6)(2c+14)
• (c+7)(2x-12)
• (c-4)(2c+21)
• 2(c+7)(c-6)

Factor completely.

121x² - 49

• ( 11x - 7 ) ²

• ( 11x - 7 ) ( 11x - 7 )

• ( 11x + 7 ) ( 11x - 7 )

• ( 12x + 7 ) ( 12x - 7 )

Factor completely.

49x² + 16

• ( 7x + 4 ) ( 7x - 4 )

• ( 7x + 4 ) ( 7x + 4 )

• ( 7x - 4 ) ²

• does not factor (SUM of squares)

What are the solutions to this equation?
(3x-2)(5x+1)=0

• x=5/2,-1/3
• x=1/5,-2/3
• x=1/3,-5/2
• x=2/3,-1/5

Use the zero product property to solve: x(24 - 8x) = 0

• x = 0, x = 3

• x = 3

• x = 0, x = -3

• x = -3

• x = 24

What are the coordinates of the vertex?

• (4,0)

• (0,0)

• (2,4)

• (0,-1)

What is an x-intercept of this parabola?

• (0, 2)

• (0, -2)

• (-2, 0)

• x=2

What is the y-intercept of this parabola?

• (0, 3)

• (0, -1)

• (-1, 0)

• (3, 0)

The domain of all parabolas is........

• 0

• 1

• x=1

• All real numbers
