Question

10a2-5a+15a3 factorizar los polinomios

Answer 1

10a² - 5a + 15a³

5a ((3a - 1) (a + 1))

5a (3a - 1) (a + 1)

Solución : 

5a (3a - 1) (a + 1)

Answer 2

$10 a^{2} -5a + 15a^{3} = 5a(2a-1+3 a^{2} )$

$5a(3 a^{2}+2a -1 ) = 5a(3a+1)(a+1)$


$3a^{2} +2a -1$
3a            -1
a             +1

3a-a = 2a

(3a-1)(a+1)
