Question

plz plz help!!!!!!!!!!......​

Answer 1

9x + 1/x = 6

9x = 6 - 1/x

9x = 6x -1 /x

9x² = 6x -1

9x² - 6x + 1

9x² - 3x - 3x +1

3x (3x-1) -1(3x-1)

(3x-1) (3x-1)

3x - 1 =0

3x = 1

X = 1/3

here is your answer....

Answer 2

Question -

9x + 1/x = 6

Answer ===>

9x = 6 - 1/x

9x = 6x - 1/x

9x² = 6x - 1

9x² - 6x + 1

Now factorise this equation,

9x² - 3x - 3x + 1

3 (3x-1) -1 (3x-1)

(3x-1) (3x-1)

Now,

3x-1 = 0

3x = 1

X = 1/3

In both cases X = 1/3

here is your answer.......
