Factorization of expression

An expression consists of terms, knotted terms and + or -.
A term consists of parts
eg 5mt consists of 3 parts, number, m and t and this term is called an mt term
235 consist of 1 part, a number and is called a number term
17bdcf consists of 5 parts, number, b, d, c, f and is called a bdcf term
A knotted term consists of bracket and it has to be untangled, expand to remove bracket

Factorization is taking out all common part in all terms

Factorise the following:

1) 4pm + 5md + 6mdp
2) 4mhd + 8mhdw

    another example of this principle:
    2(x-y)-3(y-x)
    According to BODMAS remove the Brackets frist
    2x-2y-3y-3x
    Collect similar therms
    (5y-x)
    Simplify
    5(x-y)

    (1)4pm+5md+6mdp=m(4p+5d+6dp)
    (2)4mhd+8mhdw=4mhd(1+2w)
    another e.g
    25nx+5(x+1)=5(5nx+x+1)
