Hey can you please help me posted picture of question

Answer 1

Take the square root of both sides. so D.

Answer 2

The correct answer is: Option (D) Take the square root of both sides

Step-by-step explanation:
Given equation:
9x^2 -24x + 16 = 11

Step 1:
9x^2 - 12x - 12x + 16 = 11
3x(3x - 4) - 4(3x - 4) = 11
(3x-4)^2 = 11

Step 2:
Take square-root on both sides (Option D)

`√((3x-4)^2) = √(11)`

`(3x-4) = √(11) \\ x = ( √(11) + 4 )/(3)` (value of x)
