WORKED EXAMPLE:
Collecting Like Terms
How do we collect like terms?
TERMS are separated by + or –
The sign belongs to the coefficient of the term after the symbol
If there is no symbol in front of the first term then this is a positive term
2x - 3y means +2 x's and -3 y's
“LIKE” terms must have exactly the same LETTERS AND POWERS (the
COEFFICIENT can be different)
Examples of like terms:
2x and 3x
2x2 and 3x2
2xy and 3xy
4(x + y) and 5(x + y)
Examples that are NOT like terms
