Answer 1

Step-by-step explanation:

a3−b3 can be factorised into (a−b)(a2+ab+b2)

Factoring is often a matter of looking at an expression and seeing a pattern, or recognizing something you have seen before. For example the fact that I know twenty-four is six times four is that when I learned my times tables I learned that

6∗4=24

and I can read it backwards to get

24=6∗4

The same is true for a3−b3 . I know that if I multiply

(a−b)(a2+ab+b2)

I get

(a−b)(a2+ab+b2)

=a3+a2b+ab2−a2b −ab2−b3

=a3−b3

and I can read it backwards to get

a3−b3=(a−b)(a2+ab+b2)
