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

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

Step 1

Replace all occurrences of

+

$+$

-

$-$ with a single

-

$-$ . A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because

1 \cdot - 1 = - 1

$1 \cdot - 1 = - 1$

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

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

Step 2

Subtract

11 \sqrt[3]{2 x}

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

\sqrt[3]{2 x}

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

- 10 \sqrt[3]{2 x}

$- 10 \sqrt[3]{2 x}$
