Solve 4(x^3-8)(x^2+9)(4x-x^2)/x^2-4

$$\frac { 4 ( x ^ { 3 } - 8 ) ( x ^ { 2 } + 9 ) ( 4 x - x ^ { 2 } ) } { x ^ { 2 } - 4 }$$

Evaluate

$$\frac{4x\left(4-x\right)\left(x^{2}+9\right)\left(x^{2}+2x+4\right)}{x+2}$$

Short Solution Steps

Factor the expressions that are not already factored.

$$\frac{4x\left(x-2\right)\left(-x+4\right)\left(x^{2}+9\right)\left(x^{2}+2x+4\right)}{\left(x-2\right)\left(x+2\right)}$$

Cancel out x-2 in both numerator and denominator.

$$\frac{4x\left(-x+4\right)\left(x^{2}+9\right)\left(x^{2}+2x+4\right)}{x+2}$$

Expand the expression.

$$\frac{-4x^{6}+8x^{5}-20x^{4}+136x^{3}+144x^{2}+576x}{x+2}$$

Expand

$$-\frac{4\left(x^{6}-2x^{5}+5x^{4}-34x^{3}-36x^{2}-144x\right)}{x+2}$$
