Question: 30x^3 + 18x^2  5x  3
My Answer: 6x^2(5x+3)(5x3)
Is that right. If not can you please correct my answer and tell me what to do! Thanks :)

it's wrong
you have
6x²(5x+3)(5x+3)
and you can facorize it 
So what is the right answer?

(5x+3)(6x²1)
or
(5x+3)(sqrt(6)x1)(sqrt(6)x+1) 
I believe mktintin intended to write:
(5x+3)(6x^21)
which can be further factored to obtain:
(5x+3)(sqrt(6)x1)(sqrt(6)x+1)
