In algebra, simplifying and factoring expressions are opposite processes. Simplifying an expression often means removing a pair of parentheses; factoring an expression often means applying them.
Suppose you begin with the expression 5x(2x2 – 3x + 7). To simplify this expression, you remove the parentheses by multiplying 5x by each of the three terms inside the parentheses:
= 10x3 – 15x2 + 35x
You can factor the resulting expression by replacing the parentheses: Simply divide each term by a factor of 5x:
5x(2x2 – 3x + 7)
The two forms of this expression — 5x(2x2 – 3x + 7) and 10x2 – 15x2 + 35x — are equivalent. Neither form is better than the other. But, depending upon the circumstances, one form may be more useful.

You do simplification with the help of BODMAS rule even it is in fraction or number.
B= bracket
O= of
D= division
M= multiplication
A= addition
S= subtract
You simplify with this order
HOPE THIS HELPS YOU
