[Multiply the first and last numbers: (1 x 12 = 12]
[Factor the sum of the factor (12): (-1) + (-12) = -13]
[Group]
x(x-12)-1(x-12) [Factor each group]
(x-1)(x-12) [Factor out (x-12) from both terms (GCF)]
.
Factoring is a trial-and-error process that requires a lot of practice.
Keep up the good work!!!
