2t^2 - 18t + 5t - 45
2 t^2 - 13 t -45
(t-9)(2t+5)
yes, right
2t^2 - 18t + 5t - 45
2t(t - 9) + 5 (t - 9)
(t - 9) (2t + 5)
Is this correct?

Umm, If I can remember correctly, there is only 3 terms, so you don't have to factor by grouping. I'm not sure if this is right or not but I'll try it.
I got 2t^2-23t-45
then I use FOIL
(2t - 5 )(t - 9 ) < answer

oh wait nvm i did math wrong
i think the answer is (2t + 5(t - 9)
i think the answer is (2t + 5(t - 9)
(2t + 5)(t - 9)
Did not have to factor by grouping, but it was easier that way because the grouping was given. I did it the conventional way to check.
Thanks
