factor 16a^7-14a^4-2a

factor

16 a^{7} - 14 a^{4} - 2 a

2 a (a - 1) (a^{2} + a + 1) (2 a + 1) (4 a^{2} - 2 a + 1)

Solution steps

16 a^{7} - 14 a^{4} - 2 a

Factor out common term

2 a : 2 a (8 a^{6} - 7 a^{3} - 1)

= 2 a (8 a^{6} - 7 a^{3} - 1)

Factor

8 a^{6} - 7 a^{3} - 1 : (a - 1) (a^{2} + a + 1) (2 a + 1) (2^{2} a^{2} - 2 a + 1)

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

2^{2} = 4

= 2 a (a - 1) (a^{2} + a + 1) (2 a + 1) (4 a^{2} - 2 a + 1)

9 x^{2} + 25 = 0

\frac{57}{3}

\frac{( x - 3 )}{2 x + 1} < 4

\frac{2}{7} - \frac{5}{21} \frac{1}{7}

(\frac{7}{12})^{2}
