• 2x⁸-2x²-7x
• 8x⁷-8x-28x
• 2x⁷ -2x -7

 $\frac{20x^2yz\ +15xy^2z^2}{5xyz}$  

•  $4x+3yz$  

•  $4xyz\ +\ 3xyz$  

•  $15x\ +12yz$  

•  $4x^2yz\ +3xy^2z^2$  

(24y² – 12y⁴ + 16y³) ÷ -4y³

• 
  

  $3y-4-\frac{6}{y}$

• $-3y+4+\frac{6}{y}$

• $-\frac{6}{y}+3y-4$

• $\frac{20}{y}-16y+12$

Is this division problem worked correctly?

• This is correct!
• This is incorrect!

Decide if (x-3) is a factor of 3x³+10x²-x-12

• Yes, it is a factor!
• No, it is not a factor!

Find all the factors of   x³ -3x² -4x +12 given that -2 is a zero.

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

What are the three factors for
 (x³ +7x² +7x -15) ÷ (x -1)?

• (x-1) (x+5) (x-3) 
• (x-1) (x+5) (x + 3) 
• (x+1) (x+5) (x-3) 
• (x+1) (x-5) (x-3) 

Find all the real zeros of the function 
f(x) = 2x³ - 19x² + 38x + 24 given that x-4 is a factor.

• x = 1/2, -6

• x = 4, -1/2, 6
• x = -4, 1/2, -6

if f(x) = x³+8x+24, then find f(-2) using synthetic division.

• 12
• 8
• 0
• -6
