Which of the following binomials is NOT a factor of z³-z²-12z=0?

• z-3
• z+3
• z
• z-4

Factor 9x² - 100

• (3x + 10)(3x - 10)
• (3x - 10)(3x - 10)
• (3x + 10)(3x + 10)
• (3x + 10i)(3x - 10i)

If a rectangular yard has an area of x⁴ - 3x² - 10, which could be the length and width of the yard.  

• (x² + 5) and (x² -2)
• (x⁴ - 3) and (x - 10)
• (x - 5) and (x³ + 2)
• (x² - 5) and (x² + 2)

What is the end behavior as x → +∞, f(x)→ ?

• -∞
• ∞

(2x³ + 5x² + 9) ÷ (x + 3)

• 2x² - x + 3
• 2x³ - x² + 3x
• 2x² + 11x + 33 + 108/x+3
• 2x² - 5x + 12

• y = x(x - 3)(x - 2)
• y = x(x - 3)² (x+2)
• y = x(x + 3)² (x - 2)
• y = -x(x + 3)² (x - 2)

• A
• B
• C
• D

Solve for x and y
3x + 2y = 16
7x + y = 19

• (-2,5)
• (-2,-5)
• (2,-5)
• (2,5)

5x + 3y = 6
x - 3y = 12

• (3,3)
• (-3,-3)
• (3,-3)
• (3,-2)
