3x^{2}\left(7x-2\right)+7x-2
Do the grouping 21x^{3}-6x^{2}+7x-2=\left(21x^{3}-6x^{2}\right)+\left(7x-2\right), and factor out 3x^{2} in 21x^{3}-6x^{2}.
\left(7x-2\right)\left(3x^{2}+1\right)
Factor out common term 7x-2 by using distributive property. Polynomial 3x^{2}+1 is not factored since it does not have any rational roots.
