Seth Rangel · Answer 1

5±sqrt (15)

Step-by-step explanation:

(x-5) ^2=15

Take the square root of each side

sqrt ((x-5) ^2) = ±sqrt (15)

x-5 = ±sqrt (15)

Add 5 to each side

x-5 + 5 = 5±sqrt (15)

x = 5±sqrt (15)

Isiah · Answer 2

x-5=square root of 15

x-5+5=sqrt of 15+5

x=sqrt of 15+5

thus, x=sqrt of 15+5 and x=sqrt of - 15+5
