Answer:
3(x - 2)(x - 5)
Step-by-step explanation:
Factor 3 from all terms within the trinomial:
(3x² - 21x + 30)/3 = x² - 7x + 10
3(x² - 7x + 10)
Simplify.
(x² - 7x + 10)
x -5
x -2
3(x - 2)(x - 5)* is your answer.
* remember to bring the 3 that you factored out in the beginning and stick it to the front.
