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

Question

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 :)

Answer 1

it's wrong

you have
6x²(5x+3)-(5x+3)
and you can facorize it

Answer 2

So what is the right answer?

Answer 3

(5x+3)(6x²-1)

or
(5x+3)(sqrt(6)x-1)(sqrt(6)x+1)

Answer 4

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)
