化简 a/c-b/c

解答

化简

\frac{a}{c} - \frac{b}{c}

\frac{a - b}{c}

求解步骤

\frac{a}{c} - \frac{b}{c}

使用分式法则:

\frac{a}{c} - \frac{b}{c} = \frac{a - b}{c}

= \frac{a - b}{c}

f a c t or 2 x^{3} - 4 x^{2} - 30 x

so l v e f or x, ∣ x + 10 ∣ = 3 x - 2

s im pl i f y \frac{π}{10}

so l v e f or v, ∣ v + 8 ∣ - 5 = 2

so l v e f or x, 6 (x - 1) = 9 (x + 2)
