I would do it if i had any idea what the forget i was looking at.
like terms are terms with the same thing at the end
I don't remember what it's called, but the thing I'm talking about is the variable and the exponent, if there is one
for example
5 and 7 are like terms
5y and 7 are not like terms
5y and 7y are
4y^2 and 4y are not
you can add and subtract between like terms, but you can't add or subtract unlike terms
but you can multiply and divide unlike terms
for example
5y^2 + 3y + 2y + 9y^2 = 14y^2 + 5y
5 * 7y = 35y
5 * 2y^3 = 10y^3
do you understand any better now?
