i don't understand
we factorise a number by finding the common factor. example: 2x+6 = 2 is the common factor the 2 is then put outside the bracket 2x+6 = 2(x+3)
-9(a + b)

To factorise the expression (xy + yz), you can look for common factors in the terms. Both terms share the common factor (y). Factoring (y) out gives you (y(x + z)). Thus, the factorised form is (y(x + z)).
If it does not have a common factor, you cannot factorise it!
Neither. Factorise and then multiply a subset of factors.

To factorise the expression (10x^2 - 15xy), first identify the common factors in both terms. The common factor is (5x). Factoring this out, we get: [ 10x^2 - 15xy = 5x(2x - 3y) ] Thus, the factorised form is (5x(2x - 3y)).
To factorise the expression (3X - 1), we look for common factors. In this case, there are no common factors between the two terms. Therefore, the expression is already in its simplest form and cannot be further factorised. The expression can be expressed as (1(3X - 1)), but that doesn't change its form.
To factorise the expression (3a + 6), you look for the greatest common factor (GCF) of the terms. In this case, the GCF is 3. You can factor it out to get (3(a + 2)). Thus, the factorised form of (3a + 6) is (3(a + 2)).
First you factorise it. Then you cancel out the common terms.
