------------------

3x² + 17x + 10

(2x - 1) (x + 5)

--------------------

3x² + 17x + 10

(2x - 1) (x + 5)

--------------------

(3x + 2) (x + 5)

(2x - 1)

-----------

(3x + 2)

8)

y² - 9

------------

y³ + 27

(y + 3) (y - 3)

--------------------

y³ + 27

(y + 3) (y - 3)

--------------------

(y+3) (y² - 3y + 9)

y - 3

---------------------

y² - 3y + 9

Answer 2

6. (2x - 1)

(3x + 2)

8. y - 3

y² - 3y + 9

Explanation:

6. 2x² + 9x - 5

3x² + 17x + 10

= (2x - 1) (x + 5)

3x² + 17x + 10

= (2x - 1) (x + 5)

(3x + 2) (x + 5)

= (2x - 1)

(3x + 2)

8. y² - 9

y³ + 27

= (y + 3) (y - 3)

y³ + 27

= (y + 3) (y - 3)

(y+3) (y² - 3y + 9)

= y - 3

y² - 3y + 9
