G10 Topic 3 -Review

Which would be better to use here?

• Long division
• Synthetic division

Divide using synthetic division

(2x³ + 4x² - 5) by (x + 3).

• 2x² + 2x - 4 - 12/(x + 3)

• 2x² - 2x + 6 - 23/(x + 3)

• 2x² - 2x + 8 - 20/(x + 3)

• 2x² - 4x + 1

The area of a rectangular pool table is: x² + 14x +40.

The length is x + 4. What is the width?

• x + 8

• x + 14

• x + 10

• x +4

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

• Yes, it is a factor

• No, it is not a factor

Find the remainder
(2x³ - 5x - 7) / (x + 2)

• -9
• 11
• -13
• -1

Divide:

(4x² - 24x + 35) / (2x - 5)

• 2x - 7

• 2x - 12

• 2x + 12

• 2x + 7

• (x+y)(x-y)

(x+y) ² =

• x²+y² -2xy

• x^2-y² -2xy

• x^2-y² -2xy

• x²+y² +2xy
