因式分解 2a^3+28a^2+96a

解答

因式分解

2 a^{3} + 28 a^{2} + 96 a

2 a (a + 6) (a + 8)

求解步骤

2 a^{3} + 28 a^{2} + 96 a

因式分解出通项

2 a : 2 a (a^{2} + 14 a + 48)

= 2 a (a^{2} + 14 a + 48)

因式分解

a^{2} + 14 a + 48 : (a + 6) (a + 8)

= 2 a (a + 6) (a + 8)

4 (\frac{9 + 8 x _{2}}{7}) = 10 - 3 x_{2}

x^{2} - x < 12

d o main f (x) = (\frac{1}{4})^{x}

s im pl i f y (9^{\frac{1}{2}})^{4}

f a c t or 10 x^{2} + 5
