Question

(x - 4)2 = 36 Which of the following expressions represents the solutions to the given equation? -4 ± √(36) 4 ± √(36) 16 ± √(36)

Answer 1

The answer is the second one, or 10 / -2. 

Answer 2

Option 2nd is correct.

`x=4 \pm√(36)`

Explanation:

Given the equation:

`(x-4)^2=36`

Taking square root both sides we have;

`√((x-4)^2) = \pm√(36)`

Simplify:

`x-4= \pm√(36)`

Add 4 to both sides we get;

`x=4 \pm√(36)`

Therefore, the following expressions represents the solutions to the given equation is,

`x=4 \pm√(36)`
