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

Taking all the common terms and placing them togther
ReplyDeletem(4p + 5d + 6 dp)
4mhd + 8mhdw
ReplyDeleteTaking out the common terms
mhd ( 4 + 8w)
4pm+5md+6mdp
ReplyDeletem(4p+5d+6dp)
Take out the common terms in this case it is m
4mhd+8mhdw
ReplyDeletemhd (4+8w)
mhd are the common terms.
another example of this principle:
ReplyDelete2(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)
ReplyDelete(2)4mhd+8mhdw=4mhd(1+2w)
another e.g
25nx+5(x+1)=5(5nx+x+1)
