Verify

Solution Steps

Calculate 2 to the power of 2 and get 4.

$$\left(4-2+1\right)\left(2^{2}-2-2\right)\leq 0$$

Subtract 2 from 4 to get 2.

$$\left(2+1\right)\left(2^{2}-2-2\right)\leq 0$$

Add 2 and 1 to get 3.

$$3\left(2^{2}-2-2\right)\leq 0$$

Calculate 2 to the power of 2 and get 4.

$$3\left(4-2-2\right)\leq 0$$

Subtract 2 from 4 to get 2.

$$3\left(2-2\right)\leq 0$$

Subtract 2 from 2 to get 0.

$$3\times 0\leq 0$$

Multiply 3 and 0 to get 0.

$$0\leq 0$$

Compare 0 and 0.

$$\text{true}$$
