Question

$${ x }^{ 3 } - { y }^{ 3 } - { \left(-y \right) }^{ 3 } =$$

Evaluate

$x^{3}$

Solution Steps

Expand $\left(-y\right)^{3}$.

$$x^{3}-y^{3}-\left(-1\right)^{3}y^{3}$$

Calculate $-1$ to the power of $3$ and get $-1$.

$$x^{3}-y^{3}-\left(-y^{3}\right)$$

Multiply $-1$ and $-1$ to get $1$.

$$x^{3}-y^{3}+y^{3}$$

Combine $-y^{3}$ and $y^{3}$ to get $0$.

$$x^{3}$$

Expand

$x^{3}$

Solution Steps

Expand $\left(-y\right)^{3}$.

$$x^{3}-y^{3}-\left(-1\right)^{3}y^{3}$$

Calculate $-1$ to the power of $3$ and get $-1$.

$$x^{3}-y^{3}-\left(-y^{3}\right)$$

Multiply $-1$ and $-1$ to get $1$.

$$x^{3}-y^{3}+y^{3}$$

Combine $-y^{3}$ and $y^{3}$ to get $0$.

$$x^{3}$$
