Question

Factor the following expression..
198q3r2 – 184q2r2 + 18qr2

Answer 1

what can you factor out of ALL of them?

Answer 2

uhmm... \[r ^{2}\]

Answer 3

that's one....what about the q's does each have at least 1 q?

Answer 4

what does 198, - 184, and 18 have in common?

Answer 5

Yes, that's true annnnd I'm not sure.... they all can be divided by two... orrrrr well idk

Answer 6

okay so we have r² and q so far

198/2 = 99
184/2 = 92
18/2 = 9

they cant be simplified any farther so yes

2qr²(99q² - 92q + 9)

so how can we factor this?

Answer 7

I have no idea
