Answer:
x = ± 16
Step-by-step explanation:
x^2 = 256
Take the square root of each side
sqrt(x^2) = ±sqrt(256)
x = ± 16
Answer:
± 16 , -16 and +16
Step-by-step explanation:
x^2 = 256 Take the square root on both sides and solve
x = ± 16
It can be both negative and positive because:
-16 x -16 = + 256
16 x 16 = + 256
