因式分解 Fe^2O^3+3H^2O

解答

因式分解

F e^{2} O^{3} + 3 H^{2} O

O (e^{2} F O^{2} + 3 H^{2})

求解步骤

F e^{2} O^{3} + 3 H^{2} O

使用指数法则:

a^{b + c} = a^{b} a^{c}

O^{3} = O O^{2}

= F e^{2} O O^{2} + 3 H^{2} O

因式分解出通项

O

= O (F e^{2} O^{2} + 3 H^{2})

f a c t or e^{a t} \cdot u \cdot (- t)

f a c t or x - (1)

f a c t or c i s (π)

f (x) = [arctanh (cos (x))]

f a c t or a c - 2 a d + 2 b c - 4 b d
