Question

Select all solutions to the solution to the following quadratic. (x - 2)2 = 25

Answer 1

Answer:

x = 7,    x = -3

Step-by-step explanation:

(x - 2)^2 = 25

Take the square root of each side

sqrt((x - 2)^2) =±sqrt( 25)

x-2 = ±5

Add 2 to each side

x-2+2 = 2±5

x =  2±5

x = 2+5,  x=2-5

x = 7,    x = -3
