Question

$$( { 17.31 }^{ 2 } - { 12.69 }^{ 2 } )-( { 28.81 }^{ 2 } - { 0.19 }^{ 2 } )$$

Evaluate

$-691.38$

Solution Steps

Calculate $17.31$ to the power of $2$ and get $299.6361$.

$$299.6361-12.69^{2}-\left(28.81^{2}-0.19^{2}\right)$$

Calculate $12.69$ to the power of $2$ and get $161.0361$.

$$299.6361-161.0361-\left(28.81^{2}-0.19^{2}\right)$$

Subtract $161.0361$ from $299.6361$ to get $138.6$.

$$138.6-\left(28.81^{2}-0.19^{2}\right)$$

Calculate $28.81$ to the power of $2$ and get $830.0161$.

$$138.6-\left(830.0161-0.19^{2}\right)$$

Calculate $0.19$ to the power of $2$ and get $0.0361$.

$$138.6-\left(830.0161-0.0361\right)$$

Subtract $0.0361$ from $830.0161$ to get $829.98$.

$$138.6-829.98$$

Subtract $829.98$ from $138.6$ to get $-691.38$.

$$-691.38$$

Factor

$-691.38$
