Simply the following expressions:

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

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
