Quick Check Using synthetic division to find zeros of a polynomi

• x = 0

• x = 4

• x = 9i

• x = -9i

• x = 7

• (0 , 0)

• (4 , 0)

• (9i , 0)

• (-9i , 0)

• (7 , 0)

Answer explanation

X-intercepts must be REAL

• r=6
• No, there is a remainder
• Yes, the remainder is 0
• r=12
• r=-6
• r=42
• r=-42
• r=60
• r=0
• r=-90
