Answer

$-(t-3)(3t-2)$.

Work Step by Step

The given polynomial is $=-3t^2+11t-6$ Factor out $-1$. $=-(3t^2-11t+6)$ Rewrite $-11t$ as $-9t-2t$. $=-(3t^2-9t-2t+6)$ Group the terms. $=-[(3t^2-9t)+(-2t+6)]$ Factor each group. $=-[3t(t-3)-2(t-3)]$ Factor out $(t-3)$. $=-(t-3)(3t-2)$ Hence, the factor of the polynomial is $-(t-3)(3t-2)$.
