I'm not sure if this is a method, but
Distributive Property of multiplication over addition is involved.

For easier visualization, let's treat x - 1x1 as one variable, say yy

y = x - 1y=x1


3x(x - 1) + 4(x - 1)3x(x1)+4(x1)

=> 3x(y) + 4(y)3x(y)+4(y)

=> (3x + 4)(y)(3x+4)(y)

=> (3x + 4)(x - 1)(3x+4)(x1)
