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

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

Evaluate

$$-63$$

Solution Steps

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

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

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

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

Multiply 21 and 3 to get 63.

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

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

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

Multiply 63 and -2 to get -126.

$$\frac{-126}{2}$$

Divide -126 by 2 to get -63.

$$-63$$

Factor
