For this case we have a function of the form
y = f (x), where
f (x) = (x-12) ^ 3-10

To find the real zeros we must equal zero and clear the variable "x".


(x-12) ^ 3-10 = 0

We add 10 to both sides of the equation


(x-12) ^ 3-10 + 10 = 10\\(x-12) ^ 3 = 10

We apply cube root to both sides of the equation:


\sqrt[3]{(x-12)^3} = \sqrt[3] {10}\\x-12 = \sqrt[3] {10}

We add 12 to both sides of the equation:


x-12 + 12 = \sqrt[3] {10} +12\\x = \sqrt[3] {10} +12
