-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.
The expression "negative x plus 3x" can be simplified by combining like terms. Negative x can be written as -1x, so the expression becomes -1x + 3x. When you combine -1x and 3x, you get 2x. Therefore, the simplified expression is 2x.
1xy
To simplify the expression 12p + 19q + p - 5q - 3p, we first combine like terms. Combining the p terms, we have 12p + p - 3p, which simplifies to 10p. Combining the q terms, we have 19q - 5q, which simplifies to 14q. Therefore, the simplified expression is 10p + 14q.
