Question

X^2 − 8 = 8 pls help​

Answer 1

The answer is (X=+4)

Answer 2

if you're solving for x,

start by isolating x squared to get

x^2 = 16 (we added 8 to both sides)

then square root each side:

sqrt of x^2 = x; sqrt of 16 = 4.

we end up with x = 4 (positive and neg)

if you're factoring

minus 8 from both sides to get

x^2 - 16

from there we can factor to get

(x + 4)(x - 4)
