$\frac{-2\left(x^4-16\right)}{x^3+8}$
Learn how to solve simplification of algebraic expressions problems step by step online. Simplify the expression -2/((x^3+8)/(x^4-16)). Divide fractions \frac{-2}{\frac{x^3+8}{x^4-16}} with Keep, Change, Flip: a\div \frac{b}{c}=\frac{a}{1}\div\frac{b}{c}=\frac{a}{1}\times\frac{c}{b}=\frac{a\cdot c}{b}. Factor the sum or difference of cubes using the formula: a^3\pm b^3 = (a\pm b)(a^2\mp ab+b^2). Factor the difference of squares \left(x^4-16\right) as the product of two conjugated binomials. The difference of the squares of two terms, divided by the sum of the same terms, is equal to the difference of the terms. In other words: \displaystyle\frac{a^2-b^2}{a+b}=a-b..
