Factorization
Factorization or factoring means writing a number or algebraic expression as a product of several factors, e.g.:
$$ax+bx=x(a+b)$$
To do the factorization, you need to find the greatest common factor, e.g.:
$$2x+6xy−8x^2=2x(1+3y−4x)$$
Also:
$$7x^2+7x+3x+3=$$
$$=7x(x+1)+3(x+1)=$$
$$=(7x+3)(x+1)$$
