因式分解 (2x+4)/(2x-4)

解答

因式分解

\frac{2 x + 4}{2 x - 4}

\frac{x + 2}{x - 2}

求解步骤

\frac{2 x + 4}{2 x - 4}

分解

2 x + 4 : 2 (x + 2)

= \frac{2 ( x + 2 )}{2 x - 4}

分解

2 x - 4 : 2 (x - 2)

= \frac{2 ( x + 2 )}{2 ( x - 2 )}

数字相除:

\frac{2}{2} = 1

= \frac{x + 2}{( x - 2 )}

去除括号:

(a) = a

= \frac{x + 2}{x - 2}

f a c t or (e^{x} a x sin (2 x)) d x

f a c t or - 81 + 9 x^{10}

f a c t or x \frac{1}{4} + 4

f a c t or 5^{x} (ln (2 y))

f a c t or sin^{2} (2 x^{3} + 2 x^{2})
