Question

Simply the following expressions:

Answer 1

Answer:

6.     (2x - 1)

      (3x + 2)

8.       y - 3    

     y² - 3y + 9

Step-by-step 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

Answer 2

Answer:

see below

Step-by-step 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
