(x + 8)^2 - 7 = 0(x+8)
2
−7=0

x = x

Step-by-step explanation:

I'm just gonna assume you meant to write it like this even though what you wrote makes no sense:

(x + 8)² - 7 = 0

(x + 8) 2  − 7 = 0

Since both equal zero, set them both equal to eachother and solve for x

(x + 8)² - 7 = (x + 8) 2  − 7

(x + 8)² = 2x + 16

(x + 8)(x + 8) = 2x + 16

x + 8 = x + 8

since both sides are equal, there are infinitely many solutions
