Mathematics for IGCSE & O level - Equations (Section 7 - No. 50)
When solving by factorization, what is the zero-product property?
If a product is zero, then each factor must be zero.
The sum of two factors must be zero.
The difference of two factors must be zero.
The product of factors must be one.
Explication
The zero-product property states that if ab=0 then a=0 or b=0.
