Question: 30x^3 + 18x^2 - 5x - 3


My Answer: 6x^2(5x+3)(-5x-3)

Is that right. If not can you please correct my answer and tell me what to do! Thanks :)
Answered by mk-tintin
it's wrong

you have
6x²(5x+3)-(5x+3)
and you can facorize it
Answered by Miley
So what is the right answer?
Answered by mk-tintin
(5x+3)(6x²-1)

or
(5x+3)(sqrt(6)x-1)(sqrt(6)x+1)
Answered by drwls
I believe mk-tintin intended to write:
(5x+3)(6x^2-1)

which can be further factored to obtain:
(5x+3)(sqrt(6)x-1)(sqrt(6)x+1)
