Start by writing the problem correctly. The way you wrote it,
12x+25=0, x=-25/12.
If you meant x^2+10x+25=0 then (x+5)^2=0, x=-5.

it's unfactorable, but you can solve for x, this is how you do it
combine like terms
2x + 10x = 12x
25
it gives you
12x + 25= 0
subtract 25 from both sides
12x = -25
divide by 12 on both sides
x= -25/12
thats the answer

2x^2+10x+25=0
(2x+5)(x+5)=0
2x=-5
x=-5/2 or -5

you can't factor it, you add 2x and 10x
* do you mean 2x^2? if so, then maybe it would factor, but i don't think it would
