$\sqrt[3]{2 x} - - 11 \sqrt[3]{2 x}$

Step 1

Replace all occurrences of $-$ $-$ with a single $+$ . Two consecutive minus signs have the same mathematical meaning as a single plus sign because $- 1 \cdot - 1 = 1$

$\sqrt[3]{2 x} + 11 \sqrt[3]{2 x}$

Step 2

Add $\sqrt[3]{2 x}$ and $11 \sqrt[3]{2 x}$ .

$12 \sqrt[3]{2 x}$
