HELP PLEASE :) What is the DIFFERENCE between COMBINING LIKE TERMS and using PROPERTIES OF EXPONENTS?
Margarita [4]

Answer:

Combining like terms is just that, combining numbers in an equation that have the same property. examples would be constants or numbers with the same exponent.

Properties of exponents are when you multiply, add, subtract, or divide exponents.

8x-2(x+1)=2(3x-1)<br> A. 0<br> b.2<br> C.no solution <br> D.identity
fomenos

8x - 2x(x+1) = 2(3x-1)

First, expand to remove parenthesis. / Your problem should look like:

8x - 2x - 2 = 6x - 2

Second, subtract 8x - 2x -2 to get 6x - 2. / Your problem should look like:

6x - 2 = 6x - 2

Third, both sides are equal, so there are infinite solutions. The equation is always true, meaning identity


Answer: Infinite solutions
