    5x2 – 10
    = 5 ( x2 – 2)

    This is factorising by taking out a common factor of 5 within each number.

    HELLO
    factorising is very simple, it is the opisite to simplifying so instead of multiplying out you will put the simplified expression into brackets for example:
    6pq+4hp
    now find what multiples go into 6 and 4. Number 2 goes into 6 and 4. start with putting 2 and any common letters infront of the bracets then put the remaining numbers and letters inside the brackets:
    2p(3q+2h)

    we can now check it by multiplying out
    2px3q+2px2h=6pq+4hp

    and thats it really, hope that helped
