因式分解 a^3+a^2+a

解答

因式分解

a^{3} + a^{2} + a

a (a^{2} + a + 1)

求解步骤

a^{3} + a^{2} + a

使用指数法则:

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

a^{2} = aa

= a^{2} a + aa + a

因式分解出通项

a

= a (a^{2} + a + 1)

s im pl i f y \frac{- 2.00627 + 2}{1.001 - 1}

5 x^{2} - 5 x = 0

14 m^{2} + 1 = 6 m^{2} + 7 m

3 x^{2} + 12 x + 19 = 7

\frac{x}{100} = \frac{5089.3801}{9025.7957}
