因式分解 x^2*4x

解答

因式分解

x^{2} \cdot 4 x

4 x^{3}

求解步骤

x^{2} \cdot 4 x

使用指数法则:

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

x^{2} x = x^{2 + 1}

= 4 x^{2 + 1}

数字相加:

2 + 1 = 3

= 4 x^{3}

roo t s π \cdot (r)^{2} \cdot L

f a c t or (a^{2})^{2}

f a c t or x^{2} - 2 x + 1 - (y^{2} + 4 y + 4)

f a c t or (x^{2} y^{3} z - 5 x^{6} y - 7 z) - 12

f a c t or 1 + (-)
