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)).
First you factorise it. Then you cancel out the common terms.

You take out the common factor, namely, "g".
To factorise the expression (4a + 12b), first identify the greatest common factor (GCF) of the coefficients. The GCF of 4 and 12 is 4. You can then factor out 4 from the expression: [ 4(a + 3b). ] Thus, the factorised form is (4(a + 3b)).
