Geoff divided (x⁴ + 3x² - 4x - 2) by factor of (x-2) using synthetic division. His work is shown above. Which best describes his mistake?

• Geoff wrote the remainder incorrectly.

• Geoff did not use a zero place holder for the x³ term.

• Geoff added instead of subtracting the rows.

• Geoff should have used -2 as his division since the factor was x-2.

• none of these explanations fit

• This graph has two imaginary roots because it is a polynomial of degree two.
• This graph has two imaginary roots because it has one hump.
• This graph has two imaginary roots because it touches the x-axis at two points.
• This graph is imaginary because it the graph has shifted up.
