The answer is:
- The first operation match with the polynomial:
B.
- The second operation match with the polynomial:
A.
- The third operation match with the polynomial:
C.
In order to solve the given operations, we need to group the like terms.
Remember, like terms are terms that share the same variable and the same exponent.
For example:
We only operate with the variables that shares the same exponent.
Also, we need to remember the distributive property:
So, we are given the following polynomials:
And we need to perform the following operations:
First operation,
So, the first operation match with the polynomial:
B.
Second operation,
So, the second operation match with the polynomial:
A.
Third operation,
So, the second operation match with the polynomial:
C.
Have a nice day!
