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)
(3x + 2) (x + 5)
= (2x - 1)
8. y² - 9
y³ + 27
= (y + 3) (y - 3)
(y+3) (y² - 3y + 9)
= y - 3
see below
6)
2x² + 9x - 5
------------------
(2x - 1) (x + 5)
--------------------
(2x - 1)
-----------
8)
y² - 9
------------
(y + 3) (y - 3)
y - 3
