A linear expression can only have a numeric factor that can be "taken out".
The expression will be of the form ax + b where a and b are numbers that have k as their highest common factor (HCF).
That is, a = k*c
and b = k*d
Than being the case, ax + b = kcx + kd = k*(cx + d)

Factorise fully is when brackets are involved in the equation
How does knowing one linear factor of a polynomial help find the other factors?
If you know one linear factor, then divide the polynomial by that factor. The quotient will then be a polynomial whose order (or degree) is one fewer than that of the one that you stared with. The smaller order may make it easier to factorise.
How do you factorise a²-a?
a²-a = a(a-1)
