Question

3(x - 4)^2 = 15 using the square root method.

Please and thank you.

Answer 1

Answer:

x = √5 + 4 , -√5 + 4

Step-by-step explanation:

3(x - 4)^2 = 15

/3                /3           (divide both sides by 3)

----------------------

(x - 4)^2 = 5

(x−4)^2⋅1/2 = ±√5           (take square root of both sides)

x - 4 = ±√5                      (add 4 on both sides)

  +         +4

-----------------

x = √5 + 4 , x = -√5 + 4

Answer 2

Answer:

x = √5 + 4 , -√5 + 4
