Combine like terrms:
Example Question #1 : How To Add Polynomials
Simplify the following:
Example Question #1 : Simplifying Expressions
Simplify x(4 – x) – x(3 – x).
3x
x2
0
1
x
x
You must multiply out the first set of parenthesis (distribute) and you get 4x – x2. Then multiply out the second set and you get –3x + x2. Combine like terms and you get x.
x(4 – x) – x(3 – x)
4x – x2 – x(3 – x)
4x – x2 – (3x – x2)
4x – x2 – 3x + x2 = x
Example Question #1 : Simplifying Polynomials
Simplify the following expression.
This is not a FOIL problem, as we are adding rather than multiplying the terms in parenteses.
Add like terms to solve.
Combining these terms into an expression gives us our answer.

Combine both of the terms into one expression to find the answer:
Example Question #151 : Variables
Simplify the following expression.
This is not a FOIL problem, as we are adding rather than multiplying the terms in parentheses.
Add like terms to solve.
and
have no like terms and cannot be combined with anything.
5 and -5 can be combined however:
This leaves us with .

and since
The LCM
Example Question #3 : How To Add Polynomials
Add:
First factor the denominators which gives us the following:
The two rational fractions have a common denominator hence they are like "like fractions". Hence we get:
Simplifying gives us
