Question

Arrange the following in the decreasing order based on the number of terms in the result after addition.

• A. x, -x
• B. 2x+3y,z+k
• C. x+5x,8y+3y
• D. 9x, 6y +z

Answer 1

Let's add given expressions:

1. x, -x

x-x= 0

So, number of terms = 1

2. 2x+3y,z+k

2x+3y,z+k = 2x+3y+z+k

So, number of terms = 4

3. x+5x,8y+3y

x+5x+8y+3y =6x+11y

So, number of terms = 2

4. 9x, 6y +z

9x +6y +z = 9x +6y +z .

So, number of terms = 3
