X² = 64
please help i will give brainliest

x = ± 8

Step-by-step explanation:

x² = 64

Take the square root of each side

sqrt(x^2) =± sqrt(64)

x = ± 8

To solve this equation, we first set it equal to 0 by subtracting 64.

So we have x² - 64 = 0.

Now we can factor the left as the difference of two squares.

So we have (x + 8)(x - 8) = 0.

Solving for x in each equation we have x = 8 or x = -8.

In set notation, we have {8, -8}.
