Question

Factor the trinomial. 198q^3r^2-184q^2r^2+18qr^2

Answer 1

First, go hunting for common factors.

I see a 2qr^2 for starters

2q(r^2)(99q^2-92q+9)

Can we factor the remaining trinomial? (92)^2 - 4*99*9 = 4900 = 70^2 -- So, yes, we can factor it. How would you go about that?

Answer 2

Ok....so would it be 2qr^2(1-9q)(9-11q)?

Answer 3

Please say im right........i hope.....

Answer 4

That will do.

I am a little puzzled why you did not say (9q-1)(11q-9), but I don't actually care all that much. Your response is correct.

Answer 5

So the i don't have to include the 2qr^2??

Answer 6

Do you know if it matters or not??

Answer 7

Don't throw anything away. It always matters.

Answer 8

ok..thanks!! Thought so....I have another question similar to this one but i just need you to check it if you don't mind...

Answer 9

Post a new thread.

Answer 10
