-16x + 2 + 18x
'Like' terms are those which contain the same factor; in this case 'x' So taking -16x + 18x =. 18x - 16x = 2x
So it becomes 2x + 2
NB The '2' , on its own is a constant, so is not a 'like' term.
Similarly, something like 2x^3 + 3x^2 + x^3 - x^2 .
The 'x^3' are like terms , and the 'x^2' are like terms, but 'x^3' is unlike to 'x^2'.
So collecting like terms it would become 4x^3 + 2x^2 .
When you do something like 2x^2(2x + 1) , this is NOT collecting like terms , but FACTORING.
Hope that helps!!!!!
Combine like terms. 6x - 2y +7.
There are 3 terms in the algebraic expression of: 3y+9+7x
15b + 13c - 12b + 10c + 8 = 3b + 23c + 8
2
Two of them
You combine like terms.
12t + 15
Combine like terms to give 3n + 2
Combine like terms. 6x - 2y +7.
You can combine like terms - combine the terms that have a "t" in them; separately, combine the terms that don't.
There are no like terms here.
To simplify the expression 12ab + 9ab - 7ab, you first combine like terms. The coefficients of the like terms are added or subtracted, while the variables remain the same. In this case, you add the coefficients of the like terms: 12 + 9 - 7 = 14. So, the simplified expression is 14ab.
12x+14
3x + x = 4x
There are no like terms in the expression 3x + 7
1 - 5x + 7x is an expression, not an equation (no equals sign), so you cannot solve for x. You can, however simplify (combine like terms) and get 1 + 2x.
Like terms are: 5x -7x +2x and 3 -5
