Question

$${ \left(7P \right) }^{ 2 } - { 19 }^{ 2 } -6$$

Evaluate

$49P^{2}-367$

Solution Steps

Expand $\left(7P\right)^{2}$.

$$7^{2}P^{2}-19^{2}-6$$

Calculate $7$ to the power of $2$ and get $49$.

$$49P^{2}-19^{2}-6$$

Calculate $19$ to the power of $2$ and get $361$.

$$49P^{2}-361-6$$

Subtract $6$ from $-361$ to get $-367$.

$$49P^{2}-367$$

Expand

$49P^{2}-367$

Solution Steps

Expand $\left(7P\right)^{2}$.

$$7^{2}P^{2}-19^{2}-6$$

Calculate $7$ to the power of $2$ and get $49$.

$$49P^{2}-19^{2}-6$$

Calculate $19$ to the power of $2$ and get $361$.

$$49P^{2}-361-6$$

Subtract $6$ from $-361$ to get $-367$.

$$49P^{2}-367$$
