Simply the following expressions:
Lapatulllka [165]

Answer:

6.    <u> (2x - 1) </u>

      (3x + 2)

8.   <u>     y - 3     </u>

     y² - 3y + 9

Step-by-step explanation:

6.   <u> 2x² + 9x - 5</u>

      3x² + 17x + 10

= <u>(2x - 1) (x + 5)</u>

  3x² + 17x + 10

= <u>(2x - 1)  (x + 5)</u>

  (3x + 2) (x + 5)

= <u> (2x - 1) </u>

  (3x + 2)

8.  <u>y² - 9   </u>

    y³ + 27

= <u> (y + 3) (y - 3)</u>

      y³ + 27

= <u>     (y + 3) (y - 3)     </u>

  (y+3) (y² - 3y + 9)

= <u>     y - 3     </u>

  y² - 3y + 9
