Sep 6 2015 · common factor (HCF) of the terms and insert grouping symbols usually parentheses If we expand the expression 5a(a ? 2) we obtain 5 a2 ? 10 a To factorise 5a2 ? 10 a we simply reverse the process We notice that 5a is the HCF of 5 a2 and 2 so 5 a is written outside the brackets and the remainder is written inside the brackets: 5a2 ?

How to factorise an algebraic expression?

To factorise an algebraic expression, we must determine the highest common factor (HCF) of the terms and insert grouping symbols, usually parentheses. If we expand the expression 5a(a? 2) we obtain 5a2? 10a.

How do you factorise x2+ 5x+ 6?

=x2+ (a+b)x+ab Using this result, to factorise x2+ 5x+ 6 we look for two values aand b, where a+b= 5 and ab= 6. These numbers are 2 and 3, so: x2+ 5x+ 6 = (x+ 2)(x+ 3) Expand:1(x+ 2)(x+ 3)2(a? 1)(a+ 3)3(m? 7)(m? 2)
