Option D 6(5z-2)($z^{2}$+4)
Given the polynomial $30z^{3}$ - $12z^{2}$ + 120z- 48 We see that the three terms have a common factor of 6 so we factor out a 6. 6($5z^{3}$ - $2z^{2}$ + 20z- 8) We take the GCD of the first two and the GCD of the last two terms. 6($z^{2}$(5z-2) +4(5z-2)) We take (5z-2) and factor it out which gives us. 6(5z-2)($z^{2}$+4)
