Question

Solve the equation by the square root property. (x-5)^2=15

Answer 1

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

Answer 2

5±sqrt(15)

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)
