Solve {(21(-4^2-2))/2(-4^2-2)}3(-8)

$$\{ \frac { ( 21 ( - 4 ^ { 2 } - 2 ) ) } { 2 ( - 4 ^ { 2 } - 2 ) } \} 3 ( - 8 )$$

Evaluate

$$-252$$

Solution Steps

Cancel out -4^{2}-2 in both numerator and denominator.

$$\frac{21}{2}\times 3\left(-8\right)$$

Express \frac{21}{2}\times 3 as a single fraction.

$$\frac{21\times 3}{2}\left(-8\right)$$

Multiply 21 and 3 to get 63.

$$\frac{63}{2}\left(-8\right)$$

Express \frac{63}{2}\left(-8\right) as a single fraction.

$$\frac{63\left(-8\right)}{2}$$

Multiply 63 and -8 to get -504.

$$\frac{-504}{2}$$

Divide -504 by 2 to get -252.

$$-252$$

Factor

$$-252$$
