I will do #1 then the rest follow because all of these have common factors first
2v(u^2 -9u+14)
2v(u-7)(u-2)

Always first look for a factor common to all terms
2u^2v - 18uv + 28v = 2v(u^2 - 9u + 14)
For trinomial factoring, see the leson at the link below.

1. factor out a 2v: 2v(u^2 - 9u + 14)
factor the rest: 2v(u-2)(u-7)
2. Factor out a 3u: 3u(4u^2 + 12u + 9)
Factor the rest: 3u(2u+3)^2
3. Factor out a: a(x^2-7x+12)
factor the rest: a(x-3)(x-4)
