Question 1 --

x^2 + 12x + 20

Factorizing it --

x^2 + 2x + 10x + 20 = 0 ------- Writing 12x as 10x + 2x.
x(x + 2) + 10 (x + 2) = 0 ------- Taking x as common for the first 2 parts and 10 as common for the rest 2 parts.
(x + 10)(x + 2) = 0
x = -10, x = -2.

So these are the factors ---- x = -10, x = ...
