6z^7 - 10z^6 - 24z^5
2z^5(3z^2 - 5z - 12) {remove common factor}
2z^5(3z + 4)(z - 3) {factor the trinomial}

6z^7 - 10z^6 - 24z^5
Highest common factor is 2z^5. Factor it out
6z^7 - 10z^6 - 24z^5
= 2z^5(3z^2 - 5z - 12)
= 2z^5(3z^2 - 9z + 4z - 12)
= 2z^5[3z(z - 3) + 4(z - 3)]
= 2z^5(z - 3)(3z + 4)
= 2(z^5)(z-3)(3z+4)

6z^7 - 10z^6 - 24z^5
= 2(3z^7 - 5z^6 - 12z^5)
= 2(z^5)(3z^2 - 5z - 12)
= 2(z^5)(3z + 4)(z - 3)
